【摘要】 针对白河市、须贺川市、仙台市、郡山市、福岛市等地震灾区的钢筋混凝土框架结构房屋的震害资料,分别从结构的整体破坏、梁柱构件的破坏、填充墙的破坏以及相邻建筑物碰撞等方面介绍了日本地震中钢筋混凝土框架结构典型的震害现象,震害现象表明,破坏主要集中于非结构构件的破坏。根据此次地震的震害特点,从柱铰机制、刚度突变等方面初步分析了钢筋混凝土框架结构破坏的主要原因。在此基础上,提出了若干条改善框架结构房屋抗震性能的建议,以便减轻框架结构的震害,为今后框架结构的设计和施工提供参考。更多还原

【Abstract】 The typical seismic damage phenomenon of the reinforced concrete structures are introduced after the Japanese earthquake separately from some aspects which consisted of the integral structure damage,beam-column component damage,infilled wall’s destruction,neighboring building collision and so on,in view of the seismic damage material of the reinforced concrete structures which come from Shirakawa City,Sukagawa City,Sendai City,Kooriyama City and Fukushima City,and the seismic damage phenomenon indicates that the destruction mainly concentrated in the non-structural unit.According to the characteristic of the seismic damage,the primary reason of the destruction from column hinge mechanism、sudden change of rigidity and so on is analyzed.On this basis,certain proposals about improving the seismic performance of the frame structures are put forward,in order to reduce the seismic damage and provide reference for the present design and construction.更多还原
