Abstract In this research work several high rise buildings were analyzed using CSI ETABS under the influence of the response spectrum analysis over it. Several different shaped high rise buildings such as H shaped, O shaped and C shaped buildings were taken into consideration for carrying out the research work. All three shaped buildings were of different storey that is of 12 storey and of 16 storey. For proper seismic analysis of all the above discussed buildings, response spectrum method of seismic analysis were taken into consideration. The results of all the buildings for response spectrum

Abstract:

Buildings have an essential function; they are a place for people to carry out various activities, such as social, economic, and religious activities. In a building construction plan, considering multiple factors from strength to architecture is necessary. The issue of limited land in some areas has resulted in the construction of vertical buildings, often known as high-rise buildings. High-rise building construction requires paying attention to various levels of vulnerabilities, especially for projects in earthquake-prone areas. In this study, the levels of vulnerability and vertical irregula

Architects often restrict the widths of the columns so that more free space is available and for the good aesthetic look of the building without columns protruding out of the walls and corners. This is structurally not advisable and economically feasible most of the times hence an alternate solution is required to overcome this difficulty which every structural design engineer faces. Hence non-rectangular special shaped columns have been studied and found out as an alternative to the above said problem since non-rectangular special shaped columns perform better compared to conventional rectang

Abstract: Asymmetrical plan irregularities occur when the horizontal layout of a building is non uniform or unsymmetrical in one or more axes. These irregularities may arise from variations in building shape, size, or configuration, leading to nonuniform distribution of mass, stiffness, or load paths throughout the structure. Considering equivalent static analysis (ESA) and response spectrum analysis (RSA) as per IS 1893-Part 1 (2016) considering seismic zones III, structure with square shaped plan performs better than the other shaped models (viz.

Abstract Two models have been developed to predict airflow and dispersion in urban environments. The first model, the Realistic Urban Spread and Transport of Intrusive Contaminants (RUSTIC) model, is a fast-running urban airflow code that rapidly converges to a numerical solution of a modified set of the compressible Navier–Stokes equations. RUSTIC uses the k–ω turbulence model with a buoyancy production term to handle atmospheric stability effects. The second model, “MESO,” is a Lagrangian particle transport and dispersion code that predicts concentrations of a released chemical or biological

Abstract:

The problem of atmospheric dispersion of toxic and hazardous gas in the immediate vicinity of buildings is an important topic in the preparation of safety reports for chemical sites. The test case presented in this paper represents a 'simple' example of the type of scenarios of interest. It involves a single L-shaped building on flat terrain with a continuous release of neutrally-buoyant gas from an area source in the side of the building. The area source is intended to represent the doorway of a loading bay into which a road tanker might enter to offload its contents of chemicals...

Abstract:

Progressive collapse causes the failure of primary structural member to propagate to the adjoining member, thus causing the collapse of the entire structure. The need to mitigate the impact of progressive collapse is necessary as it leads to catastrophic economic loss and causalities. The flat slab buildings are more prone to progressive collapse due to the absence of beams which are used to transfer the load initially resisted by the removed column. The main cause of failure in a flat slab building is the punching shear failure occurring at the slab column connections. The main objective of t

Abstract:

Strength based design is commonly used in the design of resisting earthquake building. It is analyzed by linear elastic method so that it can’t describe the seismic behaviour of the structures. For that reason, the design of structure needs to consider performance based design. Irregularity of structure play important role for the results of Structure Performance. This paper uses five models of 20 storey reinforced concrete building with same height(76 m) and areas(750m2) with different plan configurations: rectangular, T, L, U, and H-shaped.

The paper presents a new structural solution of the precast-monolithic frame for prefabricated residential and civil buildings of various storeys manufactured from prefabricated industrial reinforced concrete elements. The precast frame structures include L-shaped and inverted U-shaped precast elements, installed in the longitudinal and transverse directions and forming a frame, hollow-core slabs and bracing perforated beams of the outer contour, on which fencing non-bearing wall structures are supported within each storey. The computational model of the precast-monolithic building frame was d

Abstract:

A blocker of $123$-avoiding permutation matrices refers to the set of zeros contained within an $n\times n$ $123$-forcing matrix. Recently, Brualdi and Cao provided a characterization of all minimal blockers, which are blockers with a cardinality of $n$. Building upon their work, a new type of blocker, flag-shaped blockers, which can be seen as a generalization of the $L$-shaped blockers defined by Brualdi and Cao, are introduced. It is demonstrated that all flag-shaped blockers are minimum blockers. The possible cardinalities of flag-shaped blockers are also determined, and the dimensions of

Abstract:

Reinforced concrete buildings are prone to collapse during seismic events due to the brittle shear failure of non-seismic beam-column joints (BCJ). In this study, two one-third scale reinforced concrete (RC) frames incorporating various non-seismic details were tested under lateral cyclic loading. One of the RC frames was used as control, while the other was strengthened using externally bonded carbon-fiber-reinforced polymer (CFRP) sheets in a L-Shaped configuration with particular attention to anchorage to evade debonding. For the strengthening process, L-shaped CFRP sheets were bonded to th

Wind ventilation is an efficient design strategy for the natural cooling system (NCS) in humid climates. The building forms can generate different pressures and temperatures to induce natural ventilation. This study has been carried out in Rasht city, Iran in 2017. The method was performed using a computational fluid dynamic (CFD) approach simulation to study variance between the proposed and the actual results of a design. The goal of the study is to assist architects to design optimum building form for natural ventilation. Hence, the purpose of this study was to investigate the effect of the

We applied the PHOENICS software to simulate and analyze the wind environment of a traditional building skywell. Secondly, the outdoor wind environment of typical building skywells could be simulated and evaluated one by one. Finally, using the method of controlling the variables and by combining typical buildings and skywell-scale layouts, the study summarized and compared the wind environment of
