采用ABAQUS有限元软件分析了预制装配式梁的力学性能,并改变预埋钢垫板的位置及梁牛腿部位配筋率进行参数分析。研究结果表明:预制装配式梁承载性能较好,上下预埋钢垫板对结构的承载力影响较大;通过改变牛腿配筋率,可使节点具有良好的承载性能以及设计所期望的破坏模式;干式企口梁的承载力略高于现浇结构。
The mechanical properties of the prefabricated beam were analyzed by ABAQUS finite element software. The parameters of the prefabricated steel plate and the reinforcement ratio of the beam and the leg were changed. The results show that the prefabricated prefabricated beams have better bearing capacity and the upper and lower prefabricated steel backing plates have greater influence on the bearing capacity of the structure. By changing the ratio of the prefabricated prefabricated beams, the nodes can have good bearing capacity and destructive design Mode; dry-type mouth beam bearing capacity slightly higher than the cast-in-place structure.
