摘要

节点是钢管混凝土柱结构的重要部位

相关的试验研究和理论研究严重滞后.本文对最不利形式的节点-钢梁不穿心(钢梁直接焊接在钢管壁上)节点轴压性能进行了试验研究

讨论试验的基本概况、破坏现象以及轴压承载力等问题.试验结果表明

我国规程中规定公式的计算值与本次试验所得的劲性梁-钢管混凝土柱不穿心节点的节点区轴压承载力试验值基本吻合.结论可为不穿心节点轴压承载力的计算、不穿心节点的设计提供参考依据. 更多还原

Abstract

Joint is a vital area of concrete-filled steel tubular(CFST) structure.There is not a set of rounded theories of calculation and design method yet.The research work of CFST lags behind the need of practical application.As a part of fundamental research about joints of CFST columns and beams

the joint’s mechanical properties under axial compression on the base of experiment of steel about the worst joint form(steel beam is directly welded on steel tube) are introduced and can be adopted in design of similar CFST joint.The failure type and bearing capacity under axial compression are discussed here.The result shows that the bearing capacity under axial compression is identical to the result calculated by using formula recommended in rules.The conclusion can be used in the design of CFST joint.
