【摘要】 基于混凝土材料的本构理论,采用有限元方法对后张预应力钢筋混凝土梁中的预应力筋的张拉进行了仿真模拟。提出了两种不同的张拉顺序方案,并将两种方案对梁应力和变形的影响进行了比较,进行了张拉顺序的优化。更多还原

【Abstract】 Basing on the constitutive relation model of concrete,this paper simulated the tension of prestressed steel bar of post tension concrete member with FEA.Two tension schemes are introduced.By comparing the stress and deformation of the different schemes,the sequence of tension is optimized.更多还原
