| 摘 要： | 为研究锚筋和混凝土介质之间的粘结特性,利用有限元程序进行预埋钢筋混凝土梁拉拔数值模拟,得到了不同直径预埋钢筋混凝土结构内力与变形分布特征,计算表明,拉拔荷载作用下结构应力集中于混凝土梁端部,并由锚筋顶端向末端、由横截面中心向四周非线性降低,结构变形呈对称分布;特定埋深下,结构静力响应随着钢筋直径增大而减小,结构拉拔承载力增强。

| Abstract: | To investigate the bond characteristic between embedded bar and concrete,the numerical simulation of drawing performance of embed-ded reinforced concrete beam was conducted using finite element program. The endogen force and deformation distribution of the structure embed-ded with different diameter bars were obtained. The results show that the structure stress concentrates on the end of the concrete beam and de-crease nonlinearly from top end to bottom end of anchor bar and also decrease from the centre of cross-section to its boundary. The structure de-formation is symmetrical. Under certain constant embedded depth,the structure responses decrease with the diameter of the steel bar,whereas the drawing strength increases to some extent. |
