| 摘 要： | 运用ANSYS有限元软件对体外预应力加固的带缝简支梁进行了非线性有限元分析。模型中考虑了材料非线性、几何非线性和材料接触的影响。分析了模型在施加预应力及外载作用过程中应力、挠度的变化,并与尺寸相同的无缝简支梁进行了对比分析,可为体外预应力加固带缝简支梁在实际工程中应用提供参考。

| Abstract: | Nonlinear finite element analysis on reinforced concrete simple support beam with crack reinforced by Externally Prestressing Tendons is carried out through using ANSYS software.Geometric nonlinear,material nonlinear and material contact effects are considered in finite element model.Variation of stress and displacement is analyzed during applying prestress and loading and compared with the same dimensional simple support beam without crack.These can provide references for application of reinforced concrete... |
