混凝土异形柱抗震墙设计方法

Design Method of the Concrete Special-shaped Column Earthquake Proof Wall

异形柱结构的发展需要一种高效、精确的承载力求解方法．目前针对组合结构的有限元分析方法虽然比较精确，但往往存在计算速度与计算精度之间的矛盾，尤其是计算包含不同构件的结构体系．针对这一点我们经过对模型进行模态分析和拟动力试验，提出了“等效剪力墙”的设计方法．此法不但简单而且对异形柱组合结构抗震设计是偏于安全的．

The development of the special - shaped column structure needs an efficient and accurate bearing capac-ity method. At present, the finite element analysis aiming at the unit structure is accurate, but there is contradic-tion between the calculate speed and accuracy, especially when calculate the structure system including the differ-ent component. According to this, we point out the ＂equivalent shear wall design method＂ by modal analysis and pseudo - dynamic test. This method is not only simply abut also safe to the design of special - shaped column earth-quake proof wall.
