摘要
详细地介绍了某框架剪力墙结构的抗震设计。主体结构存在平面不规则性和竖向不规则性。在进行多遇水平地震作用分析时,采用CQC组合进行了谱分析,结果表明,各项指标均在规范允许的范围以内.根据结构各构件的重要性确定了性能化抗震设计目标,并通过静力弹塑性分析方法对框架梁、柱和剪力墙等重要构件的抗震性能进行了评估.结果表明。
Seismic design of a shear wall structure was illustrated in this paper.The main structure has an irregular plane.The lateral stiffness of the structure is also irregular.During normal seismic analysis,the CQC combination was used in the response spectrum analysis.It shows that the results can satisfy the code requirements.Seismic performance objectives were proposed with the consideration of the design beyond the code limits.The pushover analysis was conducted to estimate seismic performance of beams,columns and shear walls.As shown in the results,the structure can achieve performance objectives.
