可调圆弧木模板的三维有限元计算分析

3-D finite element analysis of variable circular wooden formwork

自 20 世纪 90 年代我国开始使用可调圆弧木模板以来,定型圆弧钢模板在建筑中的地位被逐步取代。由于传统的以梁代替面进行的计算,存在着过度简化计算模型的缺陷,造成计算结果与实际相差较大。所以,采用三维有限元对模板 进行计算分析,得到的计算结果经检验与实际能吻合的较好。

The variable circular wooden formwork is gradually replacing the invariable circular ferrous formwork in China since 1990s. The calculation model used conventionally has shortcomings in that it is simplified overly by substituting beam for surface; therefore, the calculation results are different from actual results greatly. Therefor, the 3-D FEM is applied to analyze the variable circular wooden formwork. The calculation results gained from the method are in accord with the actual results perfectly by verification.
