钢筋混凝土柱-钢梁柱贯穿型节点受力性能研究

摘要

The through column joint of reinforced concrete column and steel beam is an innovative type of joint detail.Based on the shear mechanism,shear strength calculation formula of the through column joint was presented and was verified by comparing the results of formula with experimental results.This paper designed new models with weak connection requirement,and some parameters affecting the behaviors of the through column joint were analyzed in details with five groups of specimens through finite element modes using ANSYS.%钢筋混凝土柱-钢梁柱贯穿型节点是钢-混凝土组合结构的一种新型节点形式.在节点抗剪机理研究的基础上,提出考虑螺栓预紧力作用的柱贯穿型节点抗剪承载力计算公式,通过已有试验对该公式进行了验证；设计一弱节点式模型,利用ANSYS对5组不同参数下的节点试件进行了有限元模拟,考察了节点受力性能的影响因素,进一步验证了所提出的抗剪公式的有效性.
