摘要
通过探讨网壳结构的地震响应和结构杆件的内力分布规律。详细分析了振型取值对地震响应的影响及矢跨比和阻尼比等主要因素对结构地震响应的影响,总结出结构响应的异同,从而得出有益于结构设计的结论,为分析结构动力响应和抗震性能奠定了理论基础。
This paper mainly discusses the seismic response of lattice shell structure and internal force distribution law of structural pole members.Influence of mode shape truncation on seismic response and influence and of main factors,such as rise-span ratio and damping ratio,on structural seismic response are analyzed in details,similarities and differences of structural response are summarized to obtain the conclusion favorable for structural design and to provide theoretical basis for analysis on structural dynamic response and anti-seismic property.
