摘要
钢结构具有良好的抗震性能,但是在多次的地震中却发生了大量的节点脆性破坏.如何通过改进构造措施改善这种情况是结构工程领域的研究热点之一,改进构造措施使塑性铰外移是一种有效防止发生脆性破坏的方式.本文分析了脆性破坏发生的原因.描述了当前对该问题的研究现状,为其以后更深层次的研究和发展提出了自己的观点.
Steel structure has superior seismic behavior,but in a number of earthquakes the fragile damage has happened in the connections. How to improve the recent situation by improve the structural measures become the key. It is effective to protect the connection from fragile damage with the method of making plastic hinge further. Introduce briefly the reason of the fragile damage and the recent developments this problem, and provide the author＇s viewpoints for the coming research.
