摘要 剪力墙是高层建筑中最常用的抗侧向荷载系统。它们具有较高的平面刚度和强度，可用于同时抵抗较大的水平载荷，同时也支撑重力载荷。因此，有必要确定剪力墙的有效且理想的位置。剪力墙布置必须绝对准确，否则反而可能造成负面影响。在该项目中，进行了一项研究，以确定添加剪力墙的效果，以及通过从根本上改变剪力墙位置来确定多层建筑的最佳结构配置。利用计算机应用软件ETABS对G+10层建筑剪力墙位置的四种不同情况进行了分析。根据印度标准规定，框架结构承受横向和重力荷载，并对结果进行分析以确定剪力墙的最佳位置。
Abstract Shear walls are the most commonly used lateral load resisting systems in high rises. They have high plane stiffness and strength which can be used to simultaneously resist large horizontal loads while also supporting gravity loads. Hence it is necessary to determine effective and ideal locations of shear walls. Shear wall arrangement must be absolutely accurate, if not, it may cause negative effects instead. In this project, a study has been carried out to determine the effects of additions of shear walls and also the optimum structural configuration of multistory buildings by changing the shear wall locations radically. Four different cases of shear wall positions for G+10 storey buildings have been analyzed by computer application software ETABS. The framed structure was subjected to lateral and gravity loading in accordance with the Indian Standards provision and the results were analyzed to determine the optimum positioning of the shear walls.
