Abstract:

The paper focuses on peculiarities of tall buildings and complexes, their typology and its formation in relation to their functional structure. The research is based on the analysis of tall buildings and complexes and identifies the following main functional elements of their formation: residential, administrative (office), hotel elements. The paper also considers the following services as «disseminated» in the space-planning structure: shops, medicine, entertainment, kids and sports facilities, etc., their location in the structure of the total bulk of the building and their impact on typological diversity. Research results include suggestions to add such concepts as «single-function tall buildings» and «mixed-use tall buildings and complexes» into the classification of tall buildings. In addition, if a single-function building or complex performs serving functions, it is proposed to add such concepts as «a residential tall building (complex) with provision of services», «an administrative (public) tall building (complex) with provision of services» into the classification of tall buildings. For mixed-use buildings and complexes the following terms are suggested: «a mixed-use tall building with provision of services», «a mixed-use tall complex with provision of services».

Abstract:

Structural efficiency of tapered tall buildings has been well recognized, and many tall buildings of tapered forms have been built throughout the world. Tall buildings are built with an enormous amount of building materials. As one of the most efficient structural forms for tall buildings, the contribution of tapered forms to saving structural materials coming from our limited natural resources could be significant. Structural design of tall buildings is generally governed by lateral stiffness rather than strength. This paper systematically studies the structural efficiency of tapered tall buildings in terms of lateral stiffness. Tall buildings of various heights and angles of taper are designed with different structural systems prevalently used for today’s tall buildings, such as diagrids, braced tubes, and core-outrigger systems. The heights of the studied buildings range from 60 to 100 stories, and the corresponding height-to-width aspect ratios in their non-tapered prismatic forms range from 6.5 to 10.8. The angles of taper studied are 1, 2, and 3 degrees. Gross floor area of each building of the same story height is maintained to be the same regardless of the different angles of taper. Based on design studies, comparative evaluation of the various structural systems for tapered tall buildings is presented.

Abstract:

The responses of tall buildings under wind loads in hilly terrain are remarkably different from that in flat terrain. Wind load codes can’t work efficiently or directly to calculate the wind-induced vibration of tall buildings in hilly terrain. Utilizing some wind tunnel test results of wind field in hilly terrain and pressures on tall buildings, the access to response of tall buildings on hilly terrain were provided. Some effects from hill characteristics to building responses were discussed.

Abstract:

Employing twisted forms in tall buildings is a relatively new architectural phenomenon, as are the cases with the Chicago Spire and Shanghai Tower. These super-tall buildings employ outrigger structures as their primary lateral load resisting systems. This paper presents structural performance of outrigger structures employed for twisted towers. Twisted tall buildings of different twisted rates are designed with outrigger structures. Two cases are studied comparatively. The first case uses spirally slanted perimeter mega-columns in response to the twisted building form. The second case uses vertical mega-columns, set back from the building perimeter, and cantilevered floor slabs from the column lines. The comparative structural efficiency of these cases is presented.

Abstract:

In 1987, the Brundtland report defined sustainable development as development that meets the needs of the present without compromising the ability of future generations to meet their own needs. The 30 percentage of the whole world greenhouse gas per year come from buildings. In many situation when architects design tall buildings, they often take into more consideration operational efficiency instead of some influence of environment. The consumption of energy ascend dramatically in developing counties, which leads to air pollutions and increase of greenhouse gas in these countries. In China, the number of tall buildings are increasing and these tall buildings take large proportion of energy consumption. The number of tall buildings was 400 until 2000 and the energy consumption of huge tall buildings is 6 to 8 times more than common buildings. Therefore, how to reduce energy consumption in tall buildings plays a vital role in sustainable development. The holistic sustainability includes three aspects which are economy, society and ecology. The purpose of this essay is critically assessing sustainable tall buildings in China and UK. Then limitation of holistic sustainability of building scale in China would be analyzed and how to enhance it.

Abstract:

Diagrid structures are widely used for today’s tall buildings due to their distinguished architectural aesthetics in any existing urban context and structural efficiency in carrying lateral loads. With prevalent emergence of complex-shaped buildings throughout the world, this paper investigates structural efficiency of diagrid structures employed for complex-shaped tall buildings, such as twisted, tilted and freeform towers. For each complex form category, tall buildings are designed with diagrid systems, and their structural efficiency is studied in conjunction with building forms. In order to investigate the impacts of various important geometric configurations of complex-shaped tall buildings, parametric models are generated using appropriate computer programs, and the models are exported to structural engineering software for design and analyses. Based on the study results, structural efficiency of diagrids for tall buildings of each complex form category is estimated.

Abstract:

The construction of a tall building in the close vicinity of existing buildings, may lead to a modification in its wind response. Therefore, the wind loads on buildings in realistic environments may be considerably different from those measured on isolated buildings. Neighboring buildings may either decrease or increase the flow-induced forces on a structure, depending mainly on the geometry and arrangement of these buildings and their orientation with respect to the direction of flow and upstream terrain conditions. This paper deals with mean and fluctuating models, as well as their spectra on a building, due to an adjacent building of side ratio 1 for wind direction from 0 to 45 degrees and the separation distance between two models. Interference effects were presented in the form of interference factors, findings were compared to analogous measurements of an isolated building.

Abstract:

Modern cities with tall building clusters can create powerful and distinctive features on the skyline more so than those with scattered tall buildings. In terms of their role in the city, tall building clusters can improve the image of the city, provide for high population density, and distinguish the urban centers. However, the planning of tall building clusters needs to be conducted using in-depth analysis in response to the spatial context to create an attractive skyline. This research attempts to compare different layouts of tall building clusters organized in circular, rectangular, and linear geographical areas. Their impact on the skyline was determined by analyzing the visibility and height transitions of these tall building clusters. Grasshopper was used to calculate the degree of surface visibility of these tall buildings from observers in urban spaces. To quantify the height transition of the cluster, the obstructed buildings were identified and mapped on the skyline viewed from a specific viewpoint. The results showed that the linear cluster had high visibility, followed by the circular and rectangular clusters. Decreasing the heights from the center to the periphery supported the focal point of the cluster.

Abstract:

Sustainable tall buildings are increasingly under rapid development and scrutiny worldwide. This will pave the way to a new generation of buildings designed in a unique form of Architectural systems integration. That is to say, finding new ways to integrate the systems, finding new common grounds and perhaps more comprehensive optimizations. The significance of integrating sustainable systems within tall buildings is the corner stone in delivering sustainable tall buildings globally. The paper looks into ways and means to better integrate passive and active renewable energy technologies and systems, green and sustainability measures into tall building’s design. Other issues such as architectural Iconography, and heritage and cultural influences on tall building’s design are also mentioned. The objective is to develop a framework for sustainable systems integration in buildings, proposing areas of further integrations customizable to any particular site context. The focus is on key sustainability strategies that drive design solutions to obtain maximum natural lighting, ventilation, heating and cooling, solar electricity/heat generation, possibility of wind energy generation and ground sourced amenities. Some design cases are presented exhibiting these strategies and design options, which clearly demonstrates the potential of tall buildings in creating a promising dense and sustainable future for cities around the globe.

Abstract:

As part of the PEER Center's Tall Building Initiative (TBI) project, practicing engineers designed three structural systems, each based on commonly used codes and guidelines, in addition to the guidelines developed by PEER. The designs were analyzed by three research teams, using a set of 75 ground-motion pairs, to predict response parameters for evaluating the performance of tall buildings. This study focuses on analytically estimating the seismic losses to these buildings to assess their relative seismic performance. The loss assessment process follows a comprehensive simulation approach that takes into account several random variables, such as building response, repair costs, etc. Throughout this study, epistemic and aleatory uncertainties in the random variables are accounted for in order to quantify those in loss estimates. Based on the dollar-loss results, the performance of the dual-system building is compared and contrasted with that of the other building systems considered in the PEER study.

Abstract:

Tall buildings are being designed and built across a wide range of cities. A poorly designed tall building can tremendously increase the building's appetite for energy. Therefore, this paper aims to determine the design strategies that help a high-rise office building to be more energy efficient. For this purpose, a comparative study on twelve case buildings in three climate groups (temperate, sub-tropical & tropical) was performed. The exterior envelope, building form and orientation, service core placement, plan layout, and special design elements like atria and sky gardens were the subject of investigation. effectiveness of different design strategies for reducing the cooling, heating, ventilation and electric lighting energy usage. Finally, lessons from these buildings' were defined for the three climates. Furthermore, a comparison of building energy performance data with international benchmarks confirmed that in temperate and sub-tropical climates sustainable design strategies for high-rise buildings were performing well, as a result leading to lower energy consumption. However, for the tropics the design of high-rise buildings needs additional consideration.

Abstract:

Outrigger system is a more popular structural system in tall buildings and higher mode participation in such buildings is an important aspect in design. During severe earthquake impacts, buildings undergo inelastic deformations, and this can lead to lengthening of modal periods of the building. Since higher mode effects have a significant impact on the overall behavior in tall buildings, the impact due to lengthening of modal periods needs to be addressed in the design. In this study, a simple assessment method is presented to quantify the effect of higher mode response on the behavior of outrigger braced buildings under seismic loads. The method comprises of simplifying the building to vertical cantilever with lateral degrees of freedom equal to number of stories and rotational springs with equivalent spring stiffness at corresponding outrigger locations. A pin-based structure was assumed to limit the first mode response to represent the transition from elastic to inelastic status of the building. The proposed method is capable of estimating the inelastic lengthened periods for higher modes and their responses in outrigger braced tall buildings. The developed method was applied to a case study outrigger braced tall building and reasonable results are predicted.

Abstract:

Most tall buildings are constructed in the prosperous center of large cities, where is inevitable to be surrounded by many interfering buildings. Wind interference effects among buildings should not be neglected. Therefore, it is necessary to investigate wind interference effects on such tall buildings. Based on the wind tunnel test of rigid model of a tall building, the wind pressure distribution on the building with interfering buildings around it has been researched, the contours of the mean and fluctuate wind pressure coefficients have also been presented. It has been found that shielding effect and channeling effect are significant in the wind interference effects on building. Wind pressure coefficients on side wall and leeward wall of a upstream building may be dramatically changed in case the wake boundary of the upstream building is interfered. The conclusions might be used as reference to structural design and plan.

Abstract:

In the aftermath of the September 11th attack, design of tall buildings particularly in the aspect of safety systems and structural robustness, arguably the most crucial issues that is deliberated till to date. Concerning the safety systems specifically on evacuation egress, many novels and innovative evacuation solutions for high rise buildings that have been researched and put forward, for instances Platform Rescue Systems (PRS), Controlled Descent Devices (CDD) and Escape Chutes. Still, the practicability of the existing proposed egress systems to be implemented in the real-life situation and its compliance with the tall building design legislation remain unknown. For developing countries such as Malaysia and United Arab Emirates, tall buildings play a role as an iconic landmark. While countries like China and Hong Kong, tall building is needed due to the scarcity of land and high populations. As more than one hundred tall structure exists in the world, and will be increasing by 2020; therefore, it is urgently needed that existing engineering practices in designing tall building to be reviewed with respect to evacuation egress. The main objective of this paper is to create awareness among developers, consultants and contractors that proper evacuation egress in tall building design and development is a must. This paper provides a comprehensive review of the existing engineering practices on tall building evacuation planning systems and design. Furthermore, the effectiveness of the currently proposed systems and its consideration amongst structural and safety engineers are also reported.

Abstract:

High rises have involved interest for engineers for as long as century. All the more along these lines, the previous thirty years have seen various structures ascending starting from the earliest stage, resisting gravity. Burj Khalifa Dubai, Taipei, Petronas twin pinnacle, Empire state building are a portion of the living instances of designing wonders. What befalls a structure when it arrives at such inconceivable statures separated from the awe that it will be, it additionally represents a gigantic measure of challenge for the auxiliary architect. Since then these structures are looked by administration stacking conditions. Two destroying powers of nature, wind and seismic tremor become truly basic for these structures. The harmony among firmness and pliability to be given turns into the controlling components to the plan of such structures. Routinely giving enough firmness against colossal burdens doesn't appear to fulfill the necessities. These structures are frequently given adequate pliability so as to disperse the gigantic measure of powers. In any case, there is a limit, with respect to how much malleability can be given in a structure. A fast figuring shows that the highest-level uprooting that can be securely borne by a 500 m tall structure is nearly 2m. The structure would not fall flat if its popular narrative dislodges by 2m. Use of different sorts of dampers and isolators have been utilized in disseminating this vitality. Much exploration has gone into advancement of TMDs, ATMDs, BTMDs, and seismic base isolators. Examination has additionally gone into different kind of investigations method as more vigorous powerful examination, weakling investigation, time history investigation and execution-based investigation. Here an endeavor has been made to explore the near benefits and negative marks of various sorts of auxiliary arrangements to comprehend their conduct under seismic and wind loads. The structure considered is of 50 stories. Different designs that have been considered incorporates propped frameworks, shear divider frameworks, dampers and isolators. The investigations results have been organized and plotted to comprehend their conduct. Time history examination and execution-based investigation by sucker investigation have additionally been concentrated to comprehend the conduct of structures.

Abstract:

Anyone concerned with the development of human civilization in the 21st Century will likely have heard the term «megacity». It is – as it should be – increasingly prevalent in both mainstream and academic discussions of the great trends of our time: urbanization, rising technological and physical connectivity, increasingly polarized extremes of wealth and poverty, environmental degradation, and climate change. It is a subject as large and far-reaching as its name implies. This paper sets the scene on how megacities and the built environment are growing together, and examines the implications for those who plan, design, develop and operate tall buildings and urban infrastructure.

Abstract:

The article deals with an actual problem of finding techniques and methods to create a comfortable urban environment. The authors emphasize that in the existing conditions of intensive urban development greater attention should be given to spatial concentration based on and more compact distribution of population in urban space. It is stressed that including mixed-use facilities into urban realm results in a significant improvement of living environment qualitative characteristics. The paper also examines modern approaches to constructing a «compact city» for comfortable and convenient living with a mixed-use tall building development. The authors explore the world's experience of designing tall mixed-use buildings and reveal modern trends in their construction. The statistics given is based on the data analysis of a group of tall mixed-use buildings consisting of more than 400 objects, constructed in 2007-2016. The research shows functional and architectural peculiarities of this typology of tall buildings and investigates a mechanism of creating zones of mixed-use tall building development in the urban structure. In conclusion, the authors consider prospects of development and major directions of improvement of mixed-use tall building parameters for a reasonable territorial urban growth and creation of high-density and comfortable building development.

Abstract:

The inter-storey drift limitation is an important index for the structural design of tall buildings. The inter-storey drift limitation of steel-hybrid structures for tall buildings is studied in this paper. It is found that it is more reasonable to divide the inter-storey drift of steel–concrete hybrid structures into harmless part and harmful part. It is meaningful to limit the harmful drift for preventing the crack of concrete walls in hybrid structures. A formula to calculate the allowable harmful inter-storey drift with no cracks of concrete walls is deduced for hybrid structures for tall buildings. The effectiveness of the formula is verified through the FEM analysis of a typical tall building hybrid structure.

Abstract:

Deformation of earth's surface caused loading of tall buildingTall buildings can cause deformations of the earth's crust for long distances from the area of their realization. Monitoring the deformation of tall big buildings from geodetic networks realised near the building can also have deformations from this point of view, and analysis of the measurements can result in false conclusions. The loading effect of the earth crust must be excluded from the measurement parameters. The paper presents a model computation of the loading effect produced by tall buildings constructed of simple geometric forms on the earth's crust.

Abstract:

This paper examines recent sustainable tall buildings in the Global South, mainly in the Middle East and China. These buildings are redefining how architects, engineers, and planners view skyscrapers, creating a new building typology in regards to function, ecology, technology, and user comfort, in the process. These “futuristic” buildings are setting new social, spatial, and environmental standards, setting a milestone in ecologically friendly architecture. Most of the reviewed projects in this paper have achieved national and international recognition from architectural and planning organizations. They represent the most recent work in the field and have exerted a profound impact on the architectural profession. This paper also summarizes the key lessons that sustainable tall buildings have brought to the field, highlighting the role of breakthrough technologies in enhancing the efficient performance and sustainability of future tall buildings.

Abstract:

Characteristics of long-period seismic ground motion and response of tall buildings are investigated in this paper to promote earthquake proof countermeasures considering the damage caused by the 2011 Tohoku earthquake. 3D finite difference method and the reciprocal theorem are used to examine the effect of sedimentary basin structures on seismic wave amplification. Natural period and damping of tall buildings are evaluated by ambient vibration tests and earthquake response observation during construction or demolition of the buildings. The effects of dynamic soil-structure interaction on response amplification of tall buildings are confirmed applying wave propagation theory to a continuum building model. Finally, a newly built base-isolated building with an isolated rooftop laboratory is introduced for full-scale long-period shaking experiment by installing actuators and jacks. Experience of long-period shaking in the building is also available with virtual reality view of indoor damage, which is effective for promotion of seismic countermeasures such as fixing furniture and safe evacuation.

Abstract:

The paper examines possibilities and limitations of application of Lidar data and digital 3D-city models to provide specialist urban analyses of tall buildings. The location and height of tall buildings is a subject of discussions, conflicts and controversies in many cities. The most important aspect is the visual influence of tall buildings to the city landscape, significant panoramas and other strategic city views. It is an actual issue in contemporary town planning worldwide. Over 50% of high-rise buildings on Earth were built in last 15 years. Tall buildings may be a threat especially for historically developed cities – typical for Europe. Contemporary Earth observation, more and more available Lidar scanning and 3D city models are a new tool for more accurate urban analysis of the tall buildings impact. The article presents appropriate simulation techniques, general assumption of geometric and computational algorithms – available methodologies and individual methods develop by author. The goal is to develop the geometric computation methods for GIS representation of the visual impact of a selected tall building to the structure of large city. In reference to this, the article introduce a Visual Impact Size method (VIS). Presented analyses were developed by application of airborne Lidar / DSM model and more processed models (like CityGML), containing the geometry and it’s semantics. Included simulations were carried out on an example of the agglomeration of Berlin.

Abstract:

Occurrence of frequency of earthquakes around the world has been increased including Sendai earthquake in Japan and magnitude of earthquake has also increased. Recently, many tall buildings using local seismic codes can be exposed to the risk of an earthquake and wind. Also, some buildings, which was planned to be built, were foundered as a result of lack of finance. Therefore, for tall buildings, structural safety such as earthquake and wind resistant performance, and financing issue are very important to progress the huge project. So we need to find another optimum alternative other than damping devices and base isolation system. In this study, four types of test specimens are used, which are fifty-story base tall building, tall building that was reinforced with diagonal brace, x-brace, and Chevron brace. And all of these cases, are subjected to the seismic load and wind load, finally analyzed and compared for seismic and wind performances.

Abstract:

Performance-based seismic design (PBSD) has been recognized as a framework for designing new buildings in the United States in recent years. Various guidelines and standards have been developed to codify and document the implementation of PBSD, including “ Seismic Evaluation and Retrofit of Existing Buildings” (ASCE 41-17), the Tall Buildings Initiative’s Guidelines for Performance-Based Seismic Design of Tall Buildings (TBI Guidelines), and the Los Angeles Tall Buildings Structural Design Council’s An Alternative Procedure for Seismic Analysis and Design of Tall Buildings Located in the Los Angeles Region (LATBSDC Procedure). The main goal of these documents is to regularize the implementation of PBSD for practicing engineers. These documents were developed independently with experts from varying backgrounds and organizations and consequently have differences in several degrees from basic intent to the details of the implementation. As the main objective of PBSD is to ensure a specified building performance, these documents would be expected to provide similar recommendations for achieving a given performance objective for new buildings. This article provides a detailed comparison among each document’s implementation of PBSD for reinforced concrete buildings, with the goal of highlighting the differences among these documents and identifying provisions in which the designed building may achieve varied performance depending on the chosen standard/guideline. This comparison can help committees developing these documents to be aware of their differences, investigate the sources of their divergence, and bring these documents closer to common ground in future cycles.

Abstract:

In a framed-tube tall building, shear wall systems are the most efficient structural systems for increasing the lateral load resistance. A novel and simple mathematical model is developed herein which calculates the natural frequencies of such tall buildings. The analyses are based on a continuous model, in which a tall building structure is replaced by an idealized cantilever beam that embodies all relevant structural characteristics. Governing equations and the corresponding eigen-problem are derived based on the energy method and Hamilton’s principle. Solutions are obtained for three examples; using the separation of variables technique implemented in MATLAB. The results are compared to SAP2000 full model analysis; and they indicate reasonable accuracy. The computed natural frequencies for structures 50, 60 and 70 storey buildings were over-estimate 7, 11 and 14 percent respectively. The computed errors indicate that the proposed method has acceptable accuracy; and can be used during the initial stages of designing of tall buildings; it is fast and low cost computational process.

Abstract:

In urban construction with the presence of tall buildings adjacent to short buildings, civil engineers have tried to connect low-rise rigid buildings to tall buildings in order to enhance the rigidity of the towers and decrease seismic response induced by earthquake excitation. From recent developments in earthquake energy dissipation systems, the application of viscous dampers for coupling of parallel and adjacent buildings to reduce earthquake effect has been considered by civil engineers, and many investigations have been conducted. In the present study an attempt has been made to evaluate the effect of connecting reinforced concrete towers to short rigid building through viscous damper devices. For this purpose, a 10-story RC tower connected to two short RC buildings by viscous damper was modeled and analyzed under Elcentro (1940) earthquake record excitation by using the finite element technique. In addition, the effect of various viscous damper damping coefficients on seismic response of the tower was evaluated by analyzing the aforementioned tower with various damper damping coefficient to the short building. The results showed improvement of seismic response of the tall building which was supported by short RC buildings through viscous damper device during earthquake. Moreover by increasing damper damping coefficient response of the tower structure the displacement was effectively reduced.

Abstract:

Since there is not much research on structural health monitoring (SHM) applications in tall buildings nowadays, this paper gives a proposal of how it can be applied on skyscrapers. Covering the whole process of SHM, this paper focuses more on the diagnostic algorithms, including Structural dynamic index method, Modal parameter identification method Neural network algorithm and Genetic algorithm and how these algorithms can be used in SHM. After introducing the basic process of SHM, an example is given to show how these principles can be applied in this over 400m building. And after all these introductions, a conclusion can be drawn that the structural health monitoring system can be applied properly in tall buildings following the way proposed in this paper.

Abstract:

With the development of our country economy, more and more super tall buildings are being built. While its beauties attract the attention of the people and they provide sufficient and comfort space to our people, it is very important to evaluate and its safety during severe earthquake. In this paper , the research method is studied for the tall structures during severer earthquake based on the design experience and research of tall structures. Based on the mechanical and deformation characteristic of this tall structure, the bottom stories and stories above the strengthened ones are selected as the "key stories" to control the performance of the building. The structure is replaced by an equivalent single degree of freedom system corresponding to each mode and each equivalent displacement is determined using the proposed method.

Abstract:

Most previous investigations have focused on the wind induced interference effects between two buildings. The interference effects of three or more buildings have seldom been studied so far due to the huge workload of experiments and data processing. In this paper, the along-wind dynamic interference effects of two and three tall buildings are investigated through a series of wind tunnel tests on typical tall building models using the high frequency force balance technique. The testing cases are totally over 8000. In order to conveniently and rapidly process the huge amount of testing data, a Windows-based software platform integrating artificial neural network, statistics and spectral computations is developed. Database technique is also employed in the platform to manage the experimental results. Because of a vast amount of experimental results, this paper presents only detailed results of the along-wind dynamic interference effects but not the across-wind effects. Some selected results of the twin-building configuration from the present tests are compared with the previous comparable results in literature. Effects of upstream terrain, height ratio and breadth ratio of the tested models on the interference factor are discussed in detail.

This paper provides a summary of a recent book by the author on urban design guidelines for integrating tall buildings in urban environments. The paper discusses the placemaking problems created by tall buildings, and simultaneously attempts to harness the potential of tall buildings to enhance placemaking. The research contends that instead of contributing to the problem of placelessness, well-designed tall buildings can rejuvenate cities, ignite economic activity, support social life and boost city pride through the science, engineering and craftsmanship embodied in these buildings. Although this study does not claim to possess all the solutions to these matters, it does propose 10 design and planning guidelines that can help to promote placemaking through tall buildings.
