摘要

主要针对梁端传递弯矩、不同加载方式、管壁厚度等对钢梁不穿心的劲性梁-钢管混凝土柱节点的节点区钢管壁受力特点的影响

以及劲性梁梁端的变形特点进行试验研究.试验结果表明

节点区钢管壁的局部变形随梁端传递弯矩的增大而增大

施加弯矩时的初始轴压越大

变形越大.但梁端传递弯矩对节点区的影响只局限于局部

节点区的轴压承载能力和工作性能基本不受影响.

Abstract

The test research work of CFST(concrete-filled steel tubular) joints is focused on the following factors: bending moment transferred way of beam

loading mode

the influence of thickness of steel tube

and the deflection property of beam.The result shows that deformation of steel tube nearing joint increases with the increment of beam end’s moment.The deformation of steel tube also increases with the increment of initial axial compression when the moment is applied.But the influence is limited to a local zone.The axial bearing capacity of joint is not influenced basically by the above factors.
