摘要
采用ANSYS对削弱度不同的钢管混凝土柱-组合梁贯穿型节点试件的应力的分布和承载能力进行了研究。结果表明:承载力随钢梁削弱度的增加而降低;塑性铰出现在节点区域以外,使节点具有良好的受力性能和一定的安全储备;节点钢梁的削弱度取值宜在0. 2~0. 4范围内。
In this paper,the ANSYS method is applied to study the stress distribution and load bearing capacity of different types of penetration connection between concrete filled tubular columns and composite beams.The results show that the bearing capacity decreases with the increase of the weakening degree of steel beam,the plastic hinge shows up outside the node area,which makes the node has good stress performance and certain safety reserve and the weakening degree of the steel beam of node should be in the range of 0.2~0.4.
