摘要
预应力张拉是预应力混凝土构件施工的重要环节 ,为考察预应力张拉时混凝土空心板的影响 ,采用多点同步张拉顺序对 30m装配式后张法预应力混凝土空心板梁进行了张拉试验。同时利用大型有限元软件ANSYS进行了有限元仿真 。
The prestressed tensioning is an important part of the prestressed concrete component construction. In order to find out the influence on concrete hollow slabs under the tensioning, the prestressed tensioning test was carried out on a 30m assembled post-tensioning concrete hollow slab under the synchronous sequence, In this paper,the process of the tensioning is simulated by the finite element analysis software ANSYS,and the variation of hollow slab's stresses and strains are discussed according to the results of the different tensioning loads.
