摘　　要：本文提出了一种新的消能支撑框架结构设汁方法，该方法能够实现罕遇地震下结构的目标位移控制，其主要设计思路是框架主体结构按非抗震设计或降低烈度进行抗震设计，消能支撑则由罕遇烈度地震下满足给定层间位移角限值的优化计算来确定。本文还给出了一个１５层框架结构的设计算例，并把本文方法的设计结果与按常现方法的设计结果进行了比较。In this paper a new design method of the energy dissipation braced frame structures has been presented. which can realize the target displacement control of the structures under the severe earthquakes. The main idea of the design method is that the enery dissipation brace system is determined by the optimization under the given story drift angle limitation and the given severe earthquakes, while the basic frame structure is designed without considering the requirements of earthquake resistance. A 15-story structure was used as an example to demonstrate the new design method. The design result is compared with that obtained by the ordinary design method.
