摘要
阐述了钢筋混凝土框架结构的延性设计原则,指出了现行抗震规范在结构设计时存在的一些问题,着重分析了框架梁跨度对"强柱弱梁"的影响。结合工程实例具体说明了由于框架梁跨度引起梁端超配筋的形成过程,并就如何减小框架梁跨度对结构抗震性能的不利影响提出了建议。
The design principles of reinforced concrete frame structure on ＂strong column-weak beam＂ is elaborated. Some problems of the current seismic specification in the structural design are pointed out, and the effects of the frame beam span on ＂strong column-weak beam＂ are analyzed. Combined with engineering examples, the reason of over reinforcement of frame beam because of the frame beam span is explained specifically, and the suggestion on reducing the adverse effect of frame beam span on seismic performance is proposed.
