某消能减震钢框架结构设计与计算分析

Structural design and analysis of a steel structure with energy dissipation devices

结合某8度区钢框架厂房工程实例,介绍了钢框架结构的消能减震设计。通过多遇地震作用下的反应谱分析和弹性时程分析、罕遇地震下的动力弹塑性时程分析,研究黏滞阻尼器耗能支撑在不同地震水准作用下的承载性能、耗能效果,并指导工程设计。

Based on an example of a steel frame factory building project in 8 degree seismic area,the energy dissipation and seismic reduction design of the steel frame structure is introduced.Through the response spectrum analysis and elastic time history analysis under frequent earthquakes,dynamic elasticplastic time history analysis under rare earthquakes,the bearing performance and the energy dissipation effect of viscous damper energy dissipation support under different seismic levels are studied,and the engineering design is guided.
