摘　　要：对门式刚架柱采取了“全焊透的焊缝”和“加劲肋锚固法”两种粘钢加固的措施锚固。通过静载试验,分析荷载位移曲线和应力曲线,证明两种锚固措施效果良好。同时,结合试验结果进行ABAQUS有限元模拟,为研究粘钢加固提供一种可行的模拟思路。In this paper,two kinds of anchoring measures are adopted,which are“full penetration butt welds”and“stiffening rib anchoring methods”for portal rigid frame column joints.Through the static load test,the analysis of the load displacement curve and stress curve proves that the two anchoring measures are effective.At the same time,the ABAQUS finite element simulation is carried out in combination with the test results,which provides a feasible simulation idea for the study of sticky steel reinforcement.
