摘要
文章设计了不同构件的截面形式和尺寸,在相关学者研究的基础上对拱形结构的弯扭屈曲进行了有限元模拟,将有限元结果与理论结果进行对比,以验证相关理论在实际工程运用中可能存在的问题。
Different sizes of components are devised in this paper.Based upon research of related scholars,FEM analysis had been carried out.The finite element results are compared with the theoretical results to verify the possible problems in the application of relevant theories in practical engineering.
