布置黏滞阻尼器的框架结构抗震性能分析

提出附设黏滞阻尼器的结构设计流程,以昆明某幼儿园工程为例,通过在结构上附设黏滞阻尼器,对比原结构和消能减震结构在地震作用下的最大层间位移角和最大层间位移,研究了高地震烈度区框架结构附设非线性黏滞阻尼器后的减震效果。结果表明:黏滞阻尼器对结构减震效果明显,合理布置黏滞阻尼器后,框架结构的抗震性能满足规范要求。研究为高地震烈度区附设黏滞阻尼器的框架结构抗震设计提供了参考。

ANALYSIS ON SEISMIC PERFORMANCE OF FRAME STRUCTURE USING VISCOUS DAMPERS

This paper proposes the structure design process with viscous dampers,taking a kindergarten in kunming project as an example,compared to the maximum story drift and story drift angle of the original structure and energy dissipation structure under seismic action,the seismic response of a frame structure with a nonlinear viscous damper in a high earthquake intensity area was researched.The results show that viscous dampers have obvious damping effect on structures,and the seismic performance of the frame structures can meet the requirements of the codes when the viscous dampers are properly arranged.The research provides a reference for seismic design of frame structures with viscous dampers in high earthquake intensity area.
