摘要：针对长3.9 m、宽2.5 m的预应力平面桁架钢筋混凝土叠合板底板以及常规钢筋桁架混凝土叠合板底板的受力性能进行了数值模拟，分析了两种叠合板底板在承载力和变形方面的差别。结果表明：预应力平面桁架钢筋混凝土叠合板底板具有很好的承载性能，其充分利用了桁架钢筋腹杆对叠合板受力贡献小的特点，在减少一半腹杆用量的条件下可以发挥与常规钢筋桁架混凝土叠合板底板相近的抗弯性能，在减轻自重的同时，体现出良好的经济性。 Abstract: Numerical simulations were carried out on the mechanical performance of the concrete composite bottom slab with prestressed plane steel bar trusses with the length of 3.9 m and the width of 2.5 m, as well as the conventional concrete composite bottom slab with steel bar trusses, and the differences in the bearing capacity and deformation of the two types of concrete composite bottom slab were analyzed. The results show that the concrete composite bottom slab with prestressed plane steel bar trusses has good load-bearing performance, and it makes full use of the feature that the web bar has little influence on the bending performance of the slab, and it can provide the bending performance similar with the conventional concrete composite bottom slab with steel bar trusses under the condition of reducing the half number of webs, which reduces its own weight and reflects good economic efficiency.

Abstract: Numerical simulations were carried out on the mechanical performance of the concrete composite bottom slab with prestressed plane steel bar trusses with the length of 3.9 m and the width of 2.5 m, as well as the conventional concrete composite bottom slab with steel bar trusses, and the differences in the bearing capacity and deformation of the two types of concrete composite bottom slab were analyzed. The results show that the concrete composite bottom slab with prestressed plane steel bar trusses has good load-bearing performance, and it makes full use of the feature that the web bar has little influence on the bending performance of the slab, and it can provide the bending performance similar with the conventional concrete composite bottom slab with steel bar trusses under the condition of reducing the half number of webs, which reduces its own weight and reflects good economic efficiency.
