【摘要】 针对汶川地震中大量框架结构出现"强梁弱柱"的震害状况,文章对比了2001版和现行2010版《抗震规范》对实现"强柱弱梁"的相关规定,分析了楼板对结构实现"强梁弱柱"屈服机制的影响并指出了规范在该方面的不足.结合欧、美、新西兰等国规范,给出了我国框架结构为实现"强柱弱梁"屈服机制而在楼板设计和施工方面的建议、措施,并为我国今后在该方面的研究指出了方向.更多还原

【Abstract】 In according with numerous strong column-weak beam damages of frame structures in Wenchuan earthquake,the related regulations of strong column-weak beam in current Seismic Design Code of Building 2010 version is compared with the 2001 version,and the reasons why strong column-weak beam would take place in structures are analyzed.The weaknesses of the Seismic Design Code of Building are also illustrated in the paper.Combined EC-8,ACI 318-02 and NZS,suggestions and methods on strong column-weak beam mechanism of frame structure design and construction are put forward and the direction of future research in this field is given.更多还原
