摘　　要：开元寺观音殿是我国典型的重檐庑殿唐式建筑,室内少柱大空间,坡屋面中额枋斗拱相互穿插、形式复杂,建筑造型限制多。采用YJK软件分别对框架-剪力墙结构、框架结构的周期、位移比等结果进行了详细对比,选择整体抗震性能好、截面满足建筑形制要求的框架-剪力墙结构体系。基于本项目坡屋面标高关系复杂且局部开洞较大导致竖向空间不连续,采用YJK软件建立不同层概念的空间模型,进行结构最大层间位移角等结果的对比分析。结果表明模型1安全、经济。采用YJK及PMSAP软件进行多遇地震作用下弹性时程分析与罕遇地震作用下弹塑性时程分析,结果表明结构各构件及整体性能满足"三水准"的抗震设防要求;同时给出了结构竖向不规则所引起的结构抗震不利的处理方法并进行计算分析。对中国传统建筑混凝土结构中存在局部易开裂及受力不明确位置提出了合理、可靠的解决措施,确保结构具有更好的使用功能和抗震性能。Guanyin Hall of Kaiyuan Temple is a typical Tang style architecture with double eaves and veranda in China, there are few columns and large space in the room, the architraves in the sloping roof are interspersed with each other, the form is complex, and the architectural modeling is limited. YJK software was used to compare the period and displacement ratio of frame-shear wall structure and frame structure in detail, and the frame-shear wall structure system with good overall seismic performance and section meeting the requirements of building shape was selected. Based on the complex relationship between the elevation of the sloping roof and the large local openings which lead to the discontinuity of the vertical space of the project, the YJK software was used to establish spatial models with different layer concepts, and the results such as the maximum inter layer displacement angle of the structure were compared and analyzed. The results show that model 1 is safe and economical. YJK and PMSAP software were used to carry out elastic time-history analysis under frequent earthquake and elastic-plastic time-history analysis under rare earthquake. The results show that that the performance of each component and the whole structure meet the seismic fortification requirements of “three levels”. At the same time, the treatment method of structural seismic disadvantage caused by structural vertical irregularity was proposed, calculated and analyzed. Reasonable and reliable solutions to the local easy cracking and unclear stress position in the concrete structure of Chinese traditional buildings were put forward, so as to ensure that the structure has better service function and seismic performance.
