钢框架刚性连接的抗震性能分析

Analysis of the Aseismatic Capability of the Beam-column Connection in Steel Frame

通常认为钢框架具有良好的抗震性能,但在最近的几次大地震中许多高层钢结构房屋的梁柱刚性连接节点受到严重破坏。这说明传统的刚性连接框架在某些方面存在不足之处。文章对刚性连接框架的形式以及抗震性能进行了深入的分析和总结,并在设计、构造、及施工三方面对提高刚性连接框架的抗震性能提出一些意见和建议。

Steel frame has nice aseismatic capability, but the rigid joints of beam column construction of highrise buildings were damaged in the Northridge earthquake and the Hanshen earthquake. It shows that there are some deficiencies in the traditional steel frame.The paper deeply analyses and summarizes the form and the shock resistant of the frames,then gives some advices on the design and the construction.
