坡屋顶的建模形式对计算结果的影响分析

Analysis of Influence of Modeling Form of Sloping Roof on the Calculation Results

不同的坡屋顶模型建立方式对于模型的计算结果有较大的影响,笔者采用当前设计行业使用人数较多的有限元分析软件PKPM,对三种坡屋顶建模形式进行了对比分析,以内力、位移等指标为依据分析了产生差异的原因,提出了坡屋顶房屋模型在建模过程中应该注意的事项,以期对设计人员提供一定的帮助。

Different models of sloping roof have great influence on the calculation results,the author uses the finite element analysis software PKPM,which is widely used in the current design industry,to make a comparative analysis of three kinds of sloping roof modeling forms.Based on the internal force,displacement and other indicators,the author analyzes the reasons for the differences,and puts forward the matters needing attention in the modeling process of sloping roof housing model,so as to provide some help for designers.
