半刚性连接具有施工方便、受力合理等优点,已逐渐应用在工程中。通过一个两层T型钢连接平面钢框架模型的拟静力试验,研究了此框架中剖分T型钢连接的变形情况、空间钢框架的耗能特性、变形特征、塑性铰出现顺序、钢框架破坏模式等,从而得到半刚性连接平面钢框架的抗震性能。结果表明:T型钢连接钢框架具有较好的变形能力和承载能力,非常适合在地震区中应用。
Semi-rigid connection has the advantages of convenient construction, reasonable force and so on, and has been gradually applied in engineering. Through the pseudo-static test of a two-layer T-steel connection plane steel frame model, the deformation of split T-section steel connection in this frame, the energy dissipation characteristics, the deformation characteristics, the appearance order of plastic hinge and the steel frame failure Mode, etc., so as to obtain the semi-rigid connection plane steel frame seismic performance. The results show that T-jointed steel frame has good deformation capacity and bearing capacity, which is very suitable for application in seismic area.
