| 摘 要： | 利用大型有限元软件ANSYS10.0对化学植筋试件进行了非线性有限元分析.分析中假定粘结应力均匀分布,分析了埋深为10 d和15 d情况下植筋的极限拉力、荷载作用下钢筋应力沿长度的变化及钢筋荷载-应变曲线并同试验结果进行了对比,计算了在不同边距和不同间距下的承载力并同已有计算公式计算结果进行对比.结果表明,在分析中可以采用粘结应力均布的模型.在考虑边距和间距对承载力影响时,可以采用喜利得公司的公式计算植筋群的受拉承载力.

| Abstract: | A nonlinear finite element method is used to confirm the assumption of the uniform bond stress distribution model.The pullout strength of 15 d and 10 d embedment depth,the stress distribution along the rebar and the rebar strain under loads are calculated and compared with the test results.The pullout strengths of bonded anchor group rebars with different rebar spacing and edge distance are also calculated and compared with the other results obtained by other formulae.According to the analysis results,the u... |
