摘　　要：针对杭州国际会议中心梁柱节点进行相关的试验研究和有限元分析。通过对其进行1/3缩尺模型跟踪测试,得到节点表面各测点的应力分布及测试值。利用AutoCAD软件建立试验节点计算模型,并采用有限元软件模拟不同受力状态下节点的弹塑性计算分析。通过比较节点表面测点实测应力值和计算分析值发现,两者吻合良好,由此可以推断节点内部应力分布及大小。最后对节点的受力性能和安全性做出评价。试验和分析计算表明,杭州国际会议中心梁柱节点是安全可靠的,节点具有充足的强度储备。An experimental study has been done on beam-column joint of Hangzhou International Conference Center. Through the 1/3 scale model experiment the strains of external considered points and the deformation of the whole beam-column joint are tested. Then, the stresses of the corresponding points can be calculated through the relationships of them. The FEM analysis model established by the Auto CAD software is also performed to compute the stresses at the same point. Through the comparison between the calculated values and the tested values, it is shown that both of the values match well. On this condition the internal stress distribution can be deduced by the FEM results. Finally, combining the test and the analysis, the mechanical behavior of the beam-column joint is revealed, as well as the safety of the joint is assessed. The beam-column joint in steel frame of Hangzhou International Conference Center is safe and reliable, and it has ample strength reservation.
