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。
This paper mainly analyzes the influence of the parameters of steel-concrete composite plate on the flexural bearing capacity of simply supported composite slab. Four groups of main parameters that affect the performance of steel-concrete composite board were analyzed by finite element software ANSYS software, including the pin spacing, the thickness of steel plate, the shear span ratio, the aspect ratio of the specimen and so on. The whole process of component loading is simulated, and the calculated results are compared with those calculated by cross-section analysis. The results show that increasing the shear connection can give full play to the material properties of steel and concrete. The increase of the thickness of the steel plate will increase the flexural capacity to different extents. The closer the loading point is to the support and the length of the composite plate The smaller the ratio, the greater the flexural capacity of the composite panel. The cross-section analysis works well for the analysis of fully sheared steel-concrete composite panels.
