摘　　要：主要分析钢板-混凝土组合板各参数对简支组合板抗弯承载性能的影响。利用有限元软件ANSYS软件对4组影响钢板-混凝土组合板性能的主要参数进行了分析,包括栓钉间距、钢板厚度、剪跨比、试件的长宽比等。模拟了构件加载的全过程,并将其计算结果与采用截面分析法的计算结果作对比。分析结果表明,提高剪力连接程度可以使钢和混凝土的材料性能得到充分发挥;钢板厚度的增加会对抗弯承载力有不同程度的提高作用;加载点越靠近支座,组合板的长宽比越小,组合板的抗弯承载力越大。截面分析法对于分析完全剪力连接的钢板-混凝土组合板效果良好。The influences of parameters of simply supported steel plate-concrete composite slabs on its flexural bearing capacity are analyzed. Numerical simulations of 4 parameter groups of steel plate-concrete composite slabs are conducted by ANSYS,including the space between studs,the thickness of steel plate,shear span ratio,lengthwidth ratio. The entire loading process is simulated,and the flexural capacities and deformations of the slabs with full shear degree are also compared with the section analysis method. The results show that the steel and the concrete presented good performances with the increase of the shear connection degree. Along with the increase of thickness of steel plate,the flexural capacity of composite slabs is enhanced at different levels. The nearer the loading point to the supports,the greater the flexural capacity of composite slab is improved. The smaller the aspect ratio is,the larger the flexural strength of composite slab is. The section analysis method can be used to analyze the flexural capacity of steel plate-concrete composite slabs full shear degree,and the results agree well with the finite element analysis.
