Abstract:

A multi-storey building is habitually modelled as a frame structure which neglects the shear wall/slab openings along with the inclusion of staircases. Furthermore, the structural strength provided by shear walls and slabs is not precisely incorporated. With increasing building height, the effect of lateral loads on a high-rise structure increases substantially. Inclusion of shear walls and slabs with the frame leads to improved lateral stiffness. Besides, their openings may play imperative role in the structural behaviour of such buildings. In this study, 61 multi-storey building configurations have been modelled. Corresponding analyses are performed to cope with the influence of shear walls, slabs, wall openings, masonry walls and staircases in addition to frame modelling. The finite element approach is used in modelling and analysis. Structural responses in each elemental combination are evaluated through equivalent static and free vibration analyses. The assessment reveals that inclusion of only slab components with frame modelling contributes trivial improvement on structural performance. Conversely, the presence of shear wall slabs with frame improves the performance noticeably. Increasing wall openings decreases the structural responses. Furthermore, it is not recommended to model staircases in addition to frame–slab–shear wall modelling, unless the effect of wall openings and slab openings is adequately considered.

Abstract:

This paper established the theoretical equations of transfer matrix method for frame shear wall structures to solve natural vibration and elastic response under earthquakes. Columns at each storey are combined into an equivalent shear member and shear walls are combined into an equivalent bending member. The structure is simplified as a double member system with the two members being coordinated by the in-plane infinite rigid floors. Transfer matrix of the structure was derived according to the fluctuated equations of equivalent members and the equilibrium and displacement compatibility conditions. After considering the boundary conditions at the bottom and top of structure, it presented the equations and method to solve seismic response, natural frequencies and modes of vibration of the structure. In comparison with FEM, it is a more convenient and universal method and is recommended for preliminary design of frame shear wall structures.

Abstract:

The basal theory of energy method is introduced, which makes use of the idea of energy balance to study the earthquake response of structures. Because of the high stiffness and low-cost of the steel frame-reinforced concrete shear wall hybrid structure, it is being widely used. But the study of the earthquake response prediction method of the structure has not been done yet. In this paper, energy method is used to study the earthquake response of the steel frame-reinforced concrete shear wall hybrid structure. A steel frame structure and a steel frame-reinforced concrete shear wall hybrid structure have been designed. The shear wall in steel frame-reinforced concrete shear wall hybrid structure is simplified as a column for easier study. In order to evaluate the results of the energy method, the time history analysis method is also used to study the earthquake response of the two structures. The shear coefficient, maximal interlaminar displacement and damage ratio of the two structures are studied. After comparison, it is found that the results of energy method and the time history analysis method are almost the same. The energy method can be easily used to study the earthquake response of the steel frame-reinforced concrete shear wall hybrid structure.

Abstract:

According to the special forms and mechanical behavior of frame-composite walls, displacement calculation method for frame-composite walls under horizontal loads is proposed in this paper. The model of frames and composite walls in parallel is adopted for considering working together of them. Cracking of filling blocks at middle and end elastic stages is taken into account. Based on material and structure mechanics theories, the displacement calculation method of frame-composite walls is derived from that of frame structures. The calculation results of the proposed method agree well with the test results of multi-grid composite wall with edge frame columns reinforced by steel. The displacement calculation method of frame-composite walls is compatible with that of frames and that of RC shear walls. The shear deformation of the frame-composite wall contributes most to the whole deformation. And the lateral displacement curves of middle to high-rise frame-composite wall structures are characterized by flexure-shear deformation. The proposed displacement calculation method for frame-composite wall structures can be used as a reference for structural design

Abstract:

This paper is to investigate the benefits of a new structural system (hereafter it is referred as “Ultra Hybrid System”) in high concrete buildings relying on the compound performance of the moment resistance frame, shear wall and infilled frame. In this case, the Ultra Hybrid System takes the advantage of the moment resistance frame and shear wall up to the height, where the wall performance reaches zero, while it is applied the infilled frame along with it. It is studied the system behavior based on using concrete-brick infilled frames in the upper floors to find out the interaction between the shear wall and infilled frame. Then, it is compared displacement, relative floor displacement, base shear, axial column loads in a hybrid system of the moment resistance frame and shear wall and the Ultra Hybrid System of the moment resistance frame, shear wall, and infilled frame. In this study, ETABS 2000 software package )Barkhordari et al., 2001) is used to model the system in compression diagonal mode. Finally, the results are presented in diagrams and tables.

Abstract:

The differences of empirical formulas of China, United States, Japan, and Europe for estimating the fundamental periods of frame-shear wall structures are investigated. Summing up paradigms of the empirical formulas from the above representation countries, the paradigm formulas expressed as single-variable exponential type, single-variable linear type, and multi-variable non-linear type. Using statistical data of 88 groups of the measured fundamental period for least-squares regression analysis, and the effect of fitting regression formula is judged by the norm of relative error‖δ‖2 , the norm of root mean square error‖RMSE‖2 , and the norm of residual mass‖CRM‖2Italic textb> . The results show that: the single-variable exponential type has wide application and gets closer with measured fundamental period; the single-variable linear type is briefly, and the single-variable based on structural height has smaller error than the single-variable of stories; the multi-variable non-linear type is very complex and larger error compared with the measured fundamental period. Considering the formula in the form of simple, practical and consistent with the codes, this paper gives single-variable exponential type as recommended empirical formula for estimating the fundamental periods of frame-shear wall structures .The proposed empirical formula can serve as a reference for revision of the seismic design code, frame-shear wall structure seismic design and related studies.

Abstract:

A finite element model (FEM) of frame-shear structure was constructed using OpenSees program based on the nonlinear flexibility theory and multi-vertical-line theory that considered bending-shear coupling, and its progressive collapse resistance under abnormal conditions was analyzed. Flexibility-based method for modeling shear wall finite element and multi-vertical-line element (SFI-MVLEM) was proposed. Method of deleting failure component elements was presented, as well as the model solving algorithm. The FEM was validated by the completed structure test. On these bases, 3 groups of typical frame-shear structure systems were designed to perform nonlinear dynamic collapse analysis under different initial failure conditions, in order to study the impact of the number of floors and earthquake resistant design on the progressive collapse resistance of frame-shear structures. Analysis results showed that, at initial failure of frame column, the residual shear wall element can well complete the internal force redistribution of structure to provide alternative force transmission path, thereby forming antiprogressive collapse force. In the case of initial failure of shear wall, C-shaped shear wall can form alternative path to diminish the vertical deformation of frame-shear structures. Final comparison shows that the structural seismic design can effectively improve their anticollapse performance.

Abstract:

Low-cycle reciprocating loading tests were carried out on a steel frame with prefabricated beam-only connected steel plate shear wall (specimen A) and a steel frame with welded beam-only connected steel plate shear wall (specimen B). The seismic performance of the two different types of steel frame-steel plate shear wall specimens was studied and the failure modes, hysteresis curve, skeleton curve, and seismic performance index, etc of two groups of specimens were obtained, together with the studies of failure characteristics, ductility, energy dissipation, and stiffness degradation of the two specimens. The results showed that the assembled steel frame-steel plate shear wall with connection joints of steel shear wall with discontinuous cover plate connected on both sides (DCPC) have good seismic performance. On the basis of no loss of seismic performance, DCPC joints can provide better energy dissipation capacity than traditional welded steel plate shear wall structures and ensure the good postearthquake repair function.

Abstract:

The cyclic tests of three one-storey spatial RC frame-shear wall structures with slabs were conducted to investigate the failure modes and the base shear-floor displacement hysteretic responses of the model structures. Then three dimensional numerical simulations were performed using the finite element program ABAQUS/Standard and ABAQUS/Explicit. The test results are detailed in this paper and compared to those of the numerical simulations. It is shown that: (a) plastic hinges initiated at the bottom of the shear wall and followed by forming near the upper ends of columns, resulting in wall-column hinges side-sway failure mechanism; (b) to a certain extent, the horizontal force bearing capacity of the structure increases with the increasing of the vertical load; (c) it is verified that the pushover results of both ABAQUS/Standard and ABAQUS/Explicit solutions agree well with the test results in the case that the parameters are reasonably chosen.

Based on the limited demand of transfer beam sectional dimension of tall building structure with transfer story in Technical Specification for Concrete Structures of Tall Building, a high-level transfer frame-shear structure with viscous dampers is presented for simulating the mechanical behavior of the key components effect with consideration the transfer beam depth with 1/6, 1/8 and 1/10 calculation span. The analysis results indicate that the internal force of the transfer beam, frame-support column of transfer story, shear wall above transfer level and base shear wall is obviously reduced, with the reduction of the transfer beam depth. Comparison with the high-level transfer frame-shear structure, the internal force of the key components of the high-level transfer frame-shear structure with viscous dampers also is reduced. Therefore, the limited demand of the transfer beam sectional dimension and the construction measure of the shear wall could be properly reduced in the high-level transfer frame-shear structure with viscous dampers.

Abstract:

The high-rise concrete residential market has been a gradually urban mainstream in recent years, and frame-shear wall structure is more used for high-rise residential structures now. This kind of structure has the advantage that the combination of frame and shear wall make the space free and flexible, and therefore the whole structure has considerable rigidity. The structure can not only satisfy the needs for people living in comfortable, but also has good dynamic and static load bearing capacity. This paper analyzed the mechanics characteristics of the structure and summarized the two kinds of main failure modes of shear wall and frame structure in earthquake. On this basis, the main principles are put forward to improve the seismic behavior of the shear wall. And further some of specific measures and suggestions which can improve the seismic performance for the frame-shear structure are introduced.

Abstract:

This study examined the racking performance of poplar laminated veneer lumber (LVL) frames using bolted steel filling plates to connect beam-column joints, poplar LVL frames using the embedment bars to connect beam-column joints, and frame-shear hybrid walls made of poplar LVL studs and oriented strand board (OSB) sheathing panels. A new design load spreader beam was used on the side of the top of a specimen to apply monotonic and cyclic loadings. It was found that the lateral force resistance, stiffness, and ultimate loads of poplar LVL pure frames with bolted steel filling plate connections and closed rod connections were much lower than those of the poplar LVL frame-shear wall hybrid structure. The highest initial stiffness of the poplar LVL hybrid frame-shear wall was 1.77 kN/mm, which was 24% and 22% lower than that of the conventional shear wall made with spruce-pine-fir studs and OSB or plywood sheathing panels, respectively. The poplar LVL frame-shear wall hybrid structure showed lower degradation in stiffness than the conventional shear wall. The hybrid frame-shear wall structures made of poplar LVL could meet the requirements of Chinese standard; however, diagonal braces were required in use of poplar LVL pure frames.

Abstract:

Shear wall structures, frame-shear wall structures and frame-tube wall structures are usually used in tall buildings, especially in China seismic regions. How to simulate the mechanical behaviors of these walls is the key to elastic-plastic analysis for tall buildings. Based on two-spring model, a nonlinear model for spatial walls is proposed. In this model, the axial, shear and flexural elastic-plastic deformation of the walls can be considered, the deformation compatibility between the wall and beam elements is also considered. The model was used to analysis the elastic-plastic behavior of spatial walls. Calculation example for verifying the model indicates that the result obtained by this method has the characteristics of fewer degrees of freedom and high accuracy. Therefore the nonlinear model for spatial walls provides a practical and efficient analysis method for tall buildings with complex type.

Abstract:

An immune genetic algorithm (IGA) is proposed to optimize the reinforced concrete (RC) frame-shear wall structures. Compared with the simple genetic algorithm (SGA), this algorithm has adaptive search capabilities for the future knowledge being used in the process of population evolution. Since the concrete grade of floors and the layout of walls are translated to binary codes, the implementation of this algorithm is not affected by the complexity of the structures. With I-typed vaccine, the continuous vertical stiffness of structure is ensured; With II-typed vaccine, the structures conforms to all the specifications which including floor shift angle, floor displacement ratio and period ratio. At the element level, the optimizing results satisfy all the specifications required by the current Chinese Codes. In this way, a computer program is created to get optimum design schemes.

In order to find the effective and reasonable reinforcement measures to adjust to the characteristics of the mixed structure, the method of equivalent stiffness should apply to the structure, it can change the original unreasonable force transmission route, and then transform and reinforce the original structure into a quasi-frame-shear wall structure whose force transmission route is similar to frame-shear wall structure.

Abstract:

Although shear walls are a widely used system for providing lateral load resistance, nonlinear analysis procedures for this type of element are much less well developed than those for frame and truss elements. Equivalent flexural models do not include shear deformation and are only suited for symmetric, straight walls. This paper describes the development of an analysis model which includes nonlinear effects for both shear and flexure. The formulation is based on a "macro" modelling approach which is suitable for complete building models in a design office environment. An analysis methodology is developed using engineering mechanics and experimental results and implemented in an existing nonlinear analysis computer program. A model is developed and validated against test results of solid walls and walls with openings. This shows that the model can capture the general characteristics of hysteretic response and the maximum strength of the wall. Results can be evaluated using acceptance criteria derived from published guidelines. An example shear wall building is then evaluated using both the nonlinear static and the nonlinear dynamic procedures. The procedure is shown to be a practical method for implementing performance based design procedures for shear wall buildings.

Abstract:

A new RC frame multi-ribbed composite walls structure is provided by using low yield strength steel. Two calculating structures are analyzed which one is the RC frame shear wall structure used as a comparison, and the other is the RC frame multi-ribbed composite walls structure. The nonlinear earthquake responses of the structures are calculated by using program IDARC2D.The nonlinear dynamic analysis models of the structures are established with retrogressive three-linear resilience model for beam, column and RC shear wall elements, while a smooth hysteretic model is proposed for representing low yield strength steel panels. The nonlinear dynamic time-history analysis of the structures under horizontal earthquake waves has been carried out. The earthquake responses of the structures and energy dissipation are studied, which provide more data information for the comprehension of earthquake responses and seismic performance of the RC frame multi-ribbed composite walls structure. The calculating results show that the low yield strength steel panels have obvious seismic mitigation effects, and that RC frame multi-ribbed composite walls structure has good seismic capacity.

Abstract:

Three single reinforcement concrete (RC) frames, including 1 reference specimen and 2 specimens strengthened with shear walls, were fabricated and subjected to low cyclic loadings, in order to evaluate seismic performances of strengthened single frame structures with exterior cantilevers. Through comparison and analysis of failure mode, hysteretic behavior, skeleton curve, energy dissipation, strength, and stiffness degradation of the tested frames, the validity of the shear wall-based reinforcement method for single frames was verified. Test results indicate that the stiffness and load-bearing capacities of strengthened frames increased considerably in comparison with the reference frame. A “strong column-weak beam” failure pattern was observed on the cantilever side, and the failure of the shear wall was always prior to the column, which can increase the structural redundancy and improve the failure mechanism and seismic performance of an existing single frame.

Abstract:

Almost all high-rise buildings have been constructed in the Republic of Armenia for past twenty-five years are Reinforced Concrete (RC) shear wall–frame structures, where shear walls provide most of the stiffness of buildings. The walls in these buildings are designed to sustain earthquake and wind loads. Vulnerability of them during earthquake action depends on many different factors. Some of them are the openings and its location in the walls. Usage of ground stories as parking and garages is demanded large openings in shear walls therefore determination of ultimate sizes of openings is important problems for designers. In this paper, FEM (Finite Element Method) models are used for investigation of stress-strain state of RC wall–frame buildings with various openings in the walls under action of seismic forces. Limitation of size and position of openings are considered in the paper taking into account of building code of Armenia. Various schemes of openings are considered in the article. The existing experimental data of shear walls were performed in various laboratories have been compared with our numerical investigation of RC models based on nonlinear computer analyses. Dynamic analyses of structures using accelerograms are showed sequence of damages in RC wall-frame models. The recommendations for limitation of ratio area of an opening to the whole area of a wall are proposed at the end of the article.

Abstract:

Based on the simulation of a eight-storey reinforced concrete(RC) frame, study has been carried out considering the rigid effect of infilled wall to explore the effect of masonry infilled on the framework by the difference of its quantity . MIDAS structural analysis software is used to make modal analysis and response spectrum analysis for the finite element models. In current chinese specification, infilled wall is often considered as nonstructual components in the buildings regardless load-supporting and shear-resistant action while the impact of rigid effect of infilled wall is not properly considered simply with the method of the reduction of structures’ vibration period. In this paper, a comparison to the current code was also made to get a better understanding of the difference between these two approaches.

Abstract:

Abstract: Structural analysis is the science of determining the effects of different loads on structures. Structural stability and stiffness are a main concern in any high-rise structures. Shear walls are structural members that are mainly responsible for resisting lateral loads predominant on structures. They are mainly responsible to increase the stiffness, reduce story drift and displacement. In order to have a comprehensive understanding about the contribution of shear wall, following research is carried out. This research involves comparing two G+16 structures; one without a shear wall and one with it. The structure has 4 bays of 3m each along X direction and Z direction. In this, we will see how shear wall resists lateral sway and reduces story drift and increases stiffness. As the height increases, the shear wall absorbs more lateral load than the frame. The software to be used for analysis is STAADPro. Keywords: STAADPro, Stiffness, storey displacement, storey drift.

Abstract:

Many frame-supported masonry shear-wall structures were observed severely damage in Wenchuan Earthquake. In this paper, an inter-story isolation system is implemented in such structures to mitigate the hazard of the earthquake. The mechanism of the mixed system is demonstrated by theoretical and numerical analysis. And it is concluded that the mass ratio, the below-stiffness ratio, the yield shear of isolated layer and the up-stiffness ratio are the main parameters whose effects are discussed separately. For the design convenience, a set of fitting equations of these parameters are provided.

Abstract:

Purpose This paper aims to propose a generalized finite element technique that can accurately approximate the solution of the flexural-shear cantilever model of wall-frame structures proposed by Heidebrecht and Stafford Smith. Design/methodology/approach This approach adopts scaled monomials as enrichment functions, and they are highly effective in accurately capturing the solution of the problem, as it consists of smooth functions such as polynomials, hyperbolic and trigonometric functions. Several numerical experiments are performed on the static and modal analyses of the flexural-shear cantilever wall-frame structures using the proposed generalized finite element method (GFEM), and their accuracies are compared with those obtained using the standard finite element method. Findings The proposed GFEM is able to achieve theoretical convergence rates of the static and modal analyses, which are, in principle, identical to those of the standard FEM, for various polynomial orders of its shape functions such as quadratic, cubic and quartic orders. The proposed GFEM with quartic enrichment functions can provide more accurate solutions than the standard FEM, and thus can be effectively used at the initial design stage of high-rise wall-frame structures. Originality/value This work is the first paper where the GFEM is applied to the analysis of high-rise wall-frame structures, and the developed technique can be used as a good analysis tool at the initial design stage.

Abstract:

Energy dissipation mechanism is very important for the structural collapse-resistant performance under strong earthquakes. Two reinforced concrete (RC) frame-shear-wall structures with different span-depth ratios in coupling beams were designed according to current Chinese seismic design code and then analyzed by nonlinear time-history analysis method under a serial of strong earthquake records. Based on the analysis results, energy dissipation mechanism and collapse-resistant performance of the two structures under strong earthquakes are studied. And the “strong wall limb-weak coupling beam” mechanism, which is achieved in the structure with larger span-depth ratio in coupling beams, is proposed to serve as the reasonable energy dissipation mechanism for RC frame-shear-wall structure. The damage of wall limb is controlled effectively under this energy dissipation mechanism, which leads to good collapse-resistant performance.

Abstract:

To further understand the seismic performance of reinforced concrete (RC) frame-shear wall structures, a 1/8 model structure is scaled from a main factory structure with seven stories and seven bays. The model with four-stories and two-bays was pseudo-dynamically tested under six earthquake actions whose peak ground accelerations (PGA) vary from 50[Formula: see text]gal to 400[Formula: see text]gal. The damage process and failure patterns were investigated. Furthermore, nonlinear dynamic analysis (NDA) and capacity spectrum method (CSM) were adopted to evaluate the seismic behavior of the model structure. The top displacement curve, story drift curve and distribution of hinges were obtained and discussed. It is shown that the model structure had the characteristics of beam-hinge failure mechanism. The two methods can be used to evaluate the seismic behavior of RC frame-shear wall structures well. What’s more, the NDA can be somewhat replaced by CSM for the seismic performance evaluation of RC structures.

Abstract:

In recent years, a variety of strengthening methods have been developed to improve the seismic performance of reinforced concrete (RC) frame structures with non-seismic details. In this regard, this study proposes a new type of seismic strengthening method that compresses prefabricated precast concrete (PC) walls from the outside of a building. In order to verify the proposed method, a RC frame structure strengthened with precast walls was fabricated, and cyclic loading tests were performed. The results showed that specimens strengthened using the proposed method exhibited further improvements in strength, stiffness and energy dissipation capacity, compared to RC frame structures with non-seismic details. In addition, a nonlinear analysis method, capable of considering the flexural compression and shear behaviors of the walls, was suggested to analytically evaluate the structural behavior of the frame structures strengthened by the proposed method. Using this, an analysis model for frame structures strengthened with precast walls was proposed. Through the proposed model, the analysis and test results were compared in relation to stiffness, strength, and energy dissipation capacity. Then, the failure mode of the column was evaluated based on the pushover analysis. In addition, this study proposed a simplified analysis model that considered the placement of longitudinal reinforcements in shear walls.

Abstract:

Recently, earthquakes occurred frequently, and our country has established a new seismic code. As the seismic intensity increases, some low frame structures cannot reach the requirements of layer displacement, layer displacement angle, stability, etc. Thus, they require reinforcement. The shear wall is good for resisting lateral force, and rational shear wall can control the shifting and shaking efficiently, thus making the distribution of internal force more reasonable. Through analysis on reinforcement and reconstruction method of adding shear walls for multi-story frame structure, the rules in terms of different layer displacement, layer displacement angle and overturning moment are found out, and the added shear wall, which can efficiently improve seismic fortification intensity, can serve as the main component for resisting lateral force. The conclusions are as follows: under earthquake action, through the method of adding shear wall, the deformation, layer displacement and layer displacement angle can be controlled effectively. Besides, the integrity and seismic behavior are inhanced, achieving the goal of improving anti-seismic grade of structure.
