带外加强环板的钢管混凝土柱脚节点受力性能试验研究
Mechanical behaviors of concrete-filled steel tubular column base joint with external annular steel plate
摘要
Abstract
Installing external annular steel plate on the concrete-filled steel tubular (CFST) column base to prevent the punching failure of CFST joint which is embedded in the reinforced concrete foundation beam. Through a short-term monotonic load static test of two scale model, studying the column base joint's failure process and failure mode, vertical ultimate bearing capacity; and the influence on the performance of column base form different locations of the external annular steel plate; and the cooperative work performance of external annular steel plate working together with concrete-filled steel tube column and the concrete. Comparing with the CFST joint without external annular steel plate, it is found that the CFST joint with external annular steel plate could effectively prevent punching failure and increase bearing capacity of the column base.关键词
