摘　　要：运用有限元结构软件SATWE通过对工程实例计算分析,研究高层建筑剪力墙结构的层高和墙厚变化对剪力墙数量的影响,得出一些参建议.考虑了层高、混凝土强度等级、墙厚三个因素对结构的影响,定量地分析了剪力墙的抗侧刚度与各个参数变化的关系以及结构自振周期、刚重比、地震剪力等这些力学特性参数的变化规律;同时,还通过调整剪力墙墙厚与层数变化来控制结构最大层间位移角不变来研究结构抗侧刚度与墙厚和层数的关系.Based on the calculation and analysis of engineering examples by finite element structural soft- ware SATWE, the effects of wall thickness and floor height in tall shear walls structure on quantity of shear walls are studied, and some reference suggestions are obtained. Taking the storey height and wall thickness on the structure into account, the paper quantitatively analyzes the relationship between stiffness of shear wall and parameters variation and the change rules of mechanical characteristics such as the ratio of rigidity-to-gravity, earthquake shear force. At the same time, the law of the change between adjustment layer number of shear wall thickness and the law under the condition of guaranteeing structure down to the condition of invariable interlayer displacement angle are also analyzed.
