【摘要】 结合克拉玛依市科技博物馆工程,对超限倾斜结构设定性能设计目标,并针对性能目标提出抗震措施及抗震构造措施.考虑结构材料的非线性属性,采用静力非线性分析方法,分析倾斜框架-剪力墙结构在地震作用下的响应,尤其是结构在罕遇地震作用下的非线性动力特性.基于罕遇地震的弹塑性时程分析表明,最大层间位移角满足1/100的限值条件.结构在罕遇地震下也是安全可靠的,剪力墙尚处在弹性范围,未出现塑性铰,形成有利的抗震防线,连梁及框架、斜撑均出现塑性铰.其中连梁的塑性程度较深,充分发挥耗能构件性能,在大震后需修复后方可使用,而框架梁及柱塑性铰程度较浅,可不经修复直接投入使用.更多还原

【Abstract】 According to Science Museum in Kelamayi,the design goal was proposed for this transfinite inclined structure.The nonlinear properties of the materials were considered,and the nonlinear analysis method was used.Seismic reaction analysis of frame-shear wall structure was carried,especially the nonlinear reaction under rare earthquake.The results under rare earthquake show that the maximum interlayer displacement angle is less than the limit value 1/100.The structure is safe and reliable under rare earthquake.Shear wall is elastic and no plastic hinge appears,useful for the development of energy dissipintion.Plastic hinges are found in coupling beams,frame beams and sprags.Plastic hinges in coupling beams have deeply developed,which are useful for the development of energy dissipation.Plastic hinges in frame beams and sprags are not so serious,and these components can be used without repairing,while the coupling beams have to be repaired after rare earthquake.更多还原
