| 摘 要： | 利用ANSYS软件对三类不同情况的简支梁进行了非线性有限元分析,介绍了有限元模型在预应力阶段、开裂和达到极限时的形态。通过有限元分析可以看出施加体外预应力后无缝梁与带缝梁承载能力都得到了提高,可见施加体外预应力来提高梁的承载能力是一种切实可行的加固措施。

| Abstract: | Based on ANSYS software nonlinear finite element analysis is carried out about three kinds of simple supported beams.Modes on models are introduced in the stage of prestressing,cracking and ultimate load.It can be seen from finite element analysis that ultimate loads of seamless beam and seam beam are increased by applying external prestress.So it is a good measure for strengthening beams by externally prestress to increase the bearing capacity. |

| Keywords: | externally prestress bearing capacity nonlinear |
