“…To make reinforced concrete buildings more earthquake-resistant, Tuken and Siddiqui suggested an analytical method to calculate the required shear wall thickness. In order to determine characteristics like story drift and displacements [4], Agarwal and S.D. Charkha [9] conducted a study on a 25-story structure in zone V after conducting preliminary research.…”

Buildings with shear walls have substantially less sway in the direction of their orientation, which results in significantly less damage to the building. Additionally, shear walls keep the roof or floor from swaying to and from by providing lateral stiffness. Walls may be particularly effective in resisting lateral stresses from wind and earthquakes when they are placed in strategic locations within a building. In this study, we model and analyse the building with varying shear wall positions using ETAB Ver. 0.2 in an effort to discover the optimal site of the shear wall in an asymmetric, irregular, star-shaped G + 14 building in zone IV. Two models, one with a shear wall and one without, have been analysed. The bare frame model has been compared to analytical results for top story displacement, base shear, time period, static eccentricity, story drift, and torsional moment.

“…The utilization of buildings with reinforced concrete shear walls (i.e., buildings with dual structural systems) is more extensive nowadays. These Reinforced Concrete structural walls are recommended by seismic codes because several research works proved their efficiency in controlling, not only the response behavior of buildings against seismic actions [1], but also in controlling the observed structural damage, which is mainly related to the distribution of such members [2]. In addition, the evaluation of buildings with shear walls has demonstrated a good balance between economy and performance, leading to an optimum design [3].…”

Reinforced concrete shear walls, which are vertically oriented plate-like elements, are efficient members in controlling the response behavior of buildings against seismic actions. In this research work, the performance of reinforced concrete buildings with shear walls having different shear wall-to-frame stiffness ratios is investigated. The considered buildings were designed in compliance with the requirements of the Algerian seismic code RPA99v2003 and were supposed to be located in regions of high seismicity. Seven 3D finite element models with different shear wall-to-frame stiffness ratios were developed and assessed using the nonlinear static analysis. Engineering Demand Parameters (EDPs) such as lateral displacement, inter-story drift ratio, shear force, and bending moment along the building height were presented. The results clarified that the induced responses can be classified into two major groups: force-based and displacement-based EDPs. Moreover, as the shear wall-to-frame ratio increases, the observed force-based EDPs increase whereas the displacement-based EDPs decrease. From a force point of view, distributing shear walls so that the packet of stiffness is lumped at the center of the building, model G with a stiffness ratio of 6.0906, amplifies the induced forces. This distribution requires more reinforcements and can lead to a conservative design. From a displacement point of view, distributing shear walls so that the packet of stiffness is lumped at the periphery of the building, model C with a stiffness ratio of 1.7879, minimizes the induced shear force and bending moment and produces the lowest values. This represents the optimum case with maximum performance and minimum strength.

“…The above requirement is di cult to satisfy unless a su cient quantity of shear is provided in the building which improves the lateral stiffness of the building. Tuken and Siddique in 2013 proposed an analytical method to determine the amount of shear wall necessary to make reinforced concrete buildings seismic resistance to severe earthquake [5]. There are several researches on the impact of shear wall on high rise building, mostly on regular buildings.…”

Shear wall provide large strength and stiffness to buildings in the direction of their orientation, which reduces sway of the building significantly and thereby reduces damage to the structure. When walls are situated in advantageous positions in a building, they may be very efficient in resisting lateral loads originating from wind or earthquakes. A framework is proposed to obtain the optimum location of shear wall for the ‘C’ shaped structure such that the torsional effect arising in the structure due to its plan irregularity is minimized. The proposal is based on the selection of optimum location that converges to the optimum structural and engineering demand parameters for a 'C' shaped structure with a fixed length of shear wall. A G + 15 story structure is considered for an illustrative example of the framework considering fourteen models of shear wall location for a ‘C’ shaped structure with a fixed length of shear wall (14.5% wall to floor area ratio). The analytical results of each model have been compared with that of bare frame model in terms of base shear, peak story displacement, peak story drift, static eccentricity, time period and torsional moment, and the optimum model is reported. The proposed framework as well as the presented example is expected to serve as the guideline for deciding the optimum location of shear walls for the ‘C’ shaped structure.
