摘　　要：异型柱结构由于其截面的特殊性,在高烈度地区使用限制较多,在使用了基础隔震技术之后,可以使上部结构地震作用产生的内力大幅度降低,在高烈度地区使用时,可以按照低烈度区进行抗震设计,并可以适当增加层高,减少钢筋的使用量,从而提高了经济效益。Because of its unique cross-section, the function of special-shaped columns frame is restricted in the high-intensity area. After the use of the base isolation technology in the design of the framework of the special-shaped columns in high-intensity area, it allows the upper structure of the earthquake generated a significant reduction in the internal force. Moreover, it can be the appropriate time to reduce the use of reinforce bar, resulting in improved economic efficiency.

关 键 词：异型柱框架 基础隔震 内力比较
