RC巨型框架结构抗震设计方法研究
Research on the seismic design of RC mega-frame structures
【摘要】 结合现行规范以及文献[2]所提出的三水准设防、三阶段设计法,对设计基本地震加速度为0.10 g地区(7度区)结构按主框架提高1度或者0.5度进行2榀巨型框架结构设计。采用弹塑性动力分析程序D rain-2d+对结构进行弹塑性地震反应分析与评价,以得出合理的设计参数。
【Abstract】 This paper begins with the structure design of the two typical plane reinforced concrete mega-frame in terms of one or half more degree according to the present codes and references[2],which state the three-level precaution and three-stages design method,and carries out elastic-plastic seism response analysis under the action of the earthquake actions regarding the 7-degree region.The elastic-plastic dynamic analysis program Drain-2d+ of the plane structure is used to get elastic-plastic time-history analysis for each typical mega-frame under the action of seism.
