| 摘 要： | 根据16个型钢混凝土标准试件和4个对比试件的推出试验,观察了构件的开裂和破坏过程,得到了荷载-滑移关系特征曲线.分析了各加载阶段沿型钢埋置长度上应变和滑移的分布规律.在对比试验中,将型钢腹板和翼缘内侧与混凝土相隔离.结果表明,型钢翼缘外侧和内侧(腹板)与混凝土之间的粘结应力在极限荷载时相差不大,而在水平残余阶段有一定差别.

| Abstract: | In this paper,according to the push-out test of 16 standard specimens and 4 contrast specimens of steel reinforced concrete,the process of the cracking and failure of the specimens were observed sowere.The characteristic curves of load-slip relationship.The distribution rules of the strain and the slip along the embedded length of the shape steel were analyzed at various load levels.In the contrastive tests,the web and the inner side of the flange were isolated from the concrete.It is shown that there are certain differences between the bond stress of the outer side of the flange and the concrete,and that of the inner side of the flange or the web and the concrete at the horizontal residual stage of loading. |
