［摘要］襄阳行政中心主楼共12层，结构高度48.1m，采用框架-剪力墙结构体系。结合建筑立面形态和平面布局，外围两排框架采用了斜框架结构，其中中庭开洞周边为单跨框架。介绍了斜框架结构的设计重点和对整体结构的影响，基于抗震性能化设计方法，进行了多遇地震作用下的弹性分析、设防烈度地震作用下关键构件的性能分析和罕遇地震下的弹塑性分析。由于结构超长，设计时考虑了温度效应的影响。分析结果表明，结构能够达到预期的设计目标。

Abstract: The main building of Xiangyang Administration Center is a 12-story building above ground with the height of 48.1m. The reinforced concrete frame and shear wall is adopted in the building. According to the facade shape and plane layout of the building, the two rows of declining frame around the outside building are used. Some single-span frames exist around the open atrium. The influence of the declining frame on the whole structure, and the performance-based seismic design of the key members and the declining frame were introduced. Based on the method of performance-base seismic design, the elastic analysis under frequent earthquake, performance analysis of key members under intermediate earthquake and elastic-plastic analysis under rare earthquake were carried out. Because of the overlong structure, temperature action was considered during structure design. The analysis results show that the structure can meet the design goals.

Keywords: declining frame-shear wall; single-span frame; performance-based seismic design; temperature effect
