摘要

强度折减系数取值是否合理关系到结构抗震设计的安全与经济,文章基于现行抗震设计规范,设计了6个单斜杆中心支撑钢框架,利用有限元软件ANSYS对各算例进行增量动力弹塑性时程分析,得出其强度折减系数值。对探讨与我国国情相适应的不同结构体系的强度折减系数有着重要的意义。
Whether the seismic behaviour factors is reasonable relates to the safety and economic for the seismic design.Based on the modern earthquake resistant standard,it is very important to propose a different seismic behaviour factors for the structural system which suits for our national basic condition.According to the correlative standard of the modern seismic design,the paper has designed six single sway rod concentrically braced steel frames,and carried on the incremental elastic-plasticity time-history analysis of the case by ANSYS,finally the value of seismic behaviour factors is given.
