摘  要:
本文在简要阐述结构稳定计算理论的基础上,利用ANSYS计算软件,在弹性材料、几何大变形条件下建立了研究腹板开洞工形截面钢拱平面内弹性极限承载力的有限元三维模型,并把极限承载力的各种影响因子设为变量,形成了整个计算过程的MAC文件。通过计算,分析出了两端铰支情况下弹性开洞钢拱的极限承载力随各种影响因子的变化规律,分析结果对钢拱的设计有参考价值。

摘  要:
Based on f the stabilitycomputation theory of structures are elaborated in brevity and in consideration of material elasticity and geometrical nonlinearity,the 3-D model of finite element in studying on in-plane elastic ultimate load-carrying capacity of工-section arches with holes in soffit is built by ANSYS software.By regarding the various influence factors of ultimateload-carrying capacity,the MAC file for whole computationprocess are formed.the law of ultimate load-carrying capacity variation of elastic steel arches with holes in web in terms of the various influence factors are extracted by analyses for for hinge-support.Some useful conclusion for the design of the steel arch are drawn.
