某砖石城门文物有限元分析

Finite Element Analysis of a Brick Stone City Gate

通过对砖石城门文物结构类型、几何尺寸测量、计算荷载确定、有限元计算模型选取和材料本构关系选取,采用有限元软件模拟计算。从主压应力、主拉应力、结构变形前后叠加等三个方面对结构进行分析,并提出相应的安全性结论。

Through the selection of structural types,geometric dimensions,calculation load determination,finite element calculation model selection and material constitutive relationship of masonry city gate cultural relic. The finite element software is used to simulate and calculate.The structure is analyzed from three aspects：principal compressive stress, principal tensile stress,and superposition before and after structural deformation,and put forward the corresponding security conclusions
