【摘要】 为研究汶川地震中钢筋混凝土框架结构震害机理,清华大学开展了钢筋混凝土框架结构拟静力倒塌的系列试验研究,包括1个3层4跨RC框架、2个关键梁柱节点和4个关键框架柱。结合试验举行了相应的数值模拟分析竞赛,并将试验和数值模拟结果全部在互联网上公布,供有关科研和工程人员参考。本文介绍了3层4跨RC整体框架的试验设计、试验过程和主要试验结果。更多还原

【Abstract】 In order to investigate the seismic damage mechanism of reinforced concrete(RC) frame structures during the Wenchuan Earthquake,a series of pseudo-static collapse experiments of RC frame structure were carried out by Tsinghua University,including one 3-story-4-span RC frame,two key beam-column joints and four key columns.Numerical prediction competition is also conducted together with the tests.The results of the experiments and numerical simulations are published on the internet,which can be freely downloaded by the researchers and engineers.The design,the experimental process and the test results of the 3-story-4-span RC frame are introduced.更多还原
