钢筋混凝土框架抗震节点统一设计方法探讨

在过去３０年里，很多国家进行了大量的地震荷载作用下钢筋混凝土框架梁柱节点及连接方面的研究工作。在试验研究的基础上，设计方法不断产生并被编入到规范中。然而关于节点的性能和设计方法却存在着不同的意见和争论，因此很难对所有问题达成共识和建立统一的设计方法。根据作者对钢筋混凝土框架节点的研究成果和对国内外资料掌握的基础上，对框架抗震节点的统一设计方法进行了初步探讨。

A UNIFIED DESIGN APPROACH TO SEISMIC JOINTS IN REINFORCED CONCRETE FRAMES

In the past thirty years,much research on beam column joints and connections in rein forced concrete frames subjected to seismic loads has been conducted in many countries Based on experimental study,design methods have been constantly developed and incorporated into some codes However,there are different opinions and arguments about behavior and design methods of joints Therefore,it is hard to reach common understanding and to develop aunified design approach for all problems According to the author's research results of joints in reinforced concrete frames and the available test materials both from home and abroad,a unified design approach to seismic joints of frames has been studied in this paper
