将隔板内连式和贯通式节点相结合并加以改进,提出了H型钢梁-钢管柱刚性连接的新型节点。该节点既克服了隔板贯通式节点下隔板宽度大于墙体影响室内美观与布置的缺点,又使梁下翼缘与柱的连接像上翼缘与柱的连接一样得到有效加强,适合在居住建筑中使用。对该节点的抗震性能进行比较系统的分析研究,包括运用非线性有限元程序ANSYS,模拟低周反复加载试验;制作多个足尺模型,进行实际的低周反复加载试验。结果表明该节点具有良好的延性和耗能能力,且塑性铰都出现在加强段以外的梁上。通过两种研究方法的比较,也可以看出有限元模拟试验是研究新型节点连接性能的有效方法,在通常情况下,能用来代替实际试验,以达到减少研究时间和研究费用的目的。
By combining and improving the inner and outer bulkheads, a new type of joint of H-beam-steel column rigid connection was proposed. The node not only overcomes the shortcomings that the width of the bulkhead under the through-through node of the bulkhead is greater than the effect of the wall on the appearance and arrangement of the interior of the indoor, but also strengthens the connection between the lower flange of the beam and the column like the connection of the upper flange and the column, Used in residential buildings. The seismic performance of the node is systematically analyzed and studied. The nonlinear finite element program ANSYS is used to simulate low-cycle repeated loading test. Multiple full-scale models are made to carry out the actual low-cycle repeated loading test. The results show that the node has good ductility and energy dissipation capacity, and the plastic hinges appear on the beams beyond the reinforced section. Through the comparison of the two methods, it can also be seen that the finite element simulation test is an effective method to study the connection performance of a new type of node. Under normal circumstances, it can be used instead of the actual test to reduce the research time and the research cost.
