摘　　要： 波形钢板结构物是几何正交异性体,分析颇为复杂。其三维模型虽能反应结构物实际形态,但在建模分析、计算及考虑影响因素上存在难度。若能采用平面模型代替三维模型,则会大大减轻工作量。通过ANSYS有限元软件对三维实体模型进行分析,采用平截面假设进行内力计算,并将计算得到的内力与二维模型的计算结果进行对比,发现两者吻合较好。因此可以采用平面模型代替三维模型对波形钢板结构物进行分析计算。 Corrugated steel plate structure is geometrical orthotropic body. The analysis is rather complicated. The 3 d model can respond the actual shape, but it is difficult for analyst to consider more factors in modeling analysis and calculation. If the structure can be simplified with a two-dimensional model, the workload would be greatly reduced. A three-dimensional is established by ANSYS finite element software, force calculation is done by using the hypothesis of flat section. In the comparing with the 2-D model, the results are coincident very well. For this reason, a two-dimensional model can be used for analysis.
