文章以某高速公路简支梁桥预应力空心板梁为例,采用有限元分析软件ANSYS对16m预应力空心板进行仿真建模,研究了预应力空心板梁从预制张力预应力到使用阶段板梁的应力状况,最后给出了相应的加固维修处置方案。
Taking a prestressed hollow slab beam of an expressway simply supported beam bridge as an example, the finite element analysis software ANSYS is used to simulate the 16m prestressed hollow slab. The influence of prestressed tensioned prestressed hollow slab beam on the prestressed tensioned hollow slab is studied. Beam stress conditions, and finally gives the corresponding reinforcement maintenance and treatment programs.
