【摘要】 以地处地震高烈度区的宿迁建设大厦为例,在传统的框架-抗震墙结构体系的基础上设置局部消能支撑,进行了结构非线性时程分析,对消能装置的数量及布置进行了优化,分析结果表明,框架-抗震墙结构+局部消能减震支撑在多遇地震作用下的层间位移能满足《建筑抗震设计规范》要求,在罕遇地震作用下具有更高的安全储备,表现出良好的抗震性能。同时合理的构造措施也为消能支撑发挥作用提供了可靠保证,可为高烈度区类似结构的设计提供借鉴。更多还原

【Abstract】 Based on Suqian Construction Building,which locates in a region of high earthquake intensity.The local energy-dissipation braces is used on the foundation of the ordinary frame-shear wall structure system in this paper.The optimum number and location of the energy-dissipated braces in this building are studied.Calculation results of the nonlinear time-history analysis by SAP2000N software show that,the frame-shear wall and energy-dissipation braces structure system can satisfy the requirements of "Code for seismic design of buildings",possess higher safety under seldom occurring earthquake,and has excellent aseismic behaviors.At the same time,the energy-dissipation braces can be effective by the rational construct measures.The design method suggested in this paper can be utilised for the design of similar projects in the region of high earthquake intensity.更多还原
