【摘要】 针对临沂拱门天廊高大跨拱结构,其拱顶平台起到传力枢纽的作用,在拱结构中处于关键地位,本文利用大型通用有限元软件ABAQUS 6.14对该拱结构的拱顶平台进行了有限元分析,确定了有限元分析原则和分析方法,得到了该拱顶平台在1.0倍、1.35倍、2.0倍最不利荷载工况组合下的应力云图。结果表明该平台在1.0倍和1.35倍荷载下处于弹性阶段,2.0倍荷载下局部屈服,该拱顶平台具有良好的承载能力和安全储备,设计安全可靠。更多还原

【Abstract】 Aiming at the long-span arch structure of Linyi Arch gallery, its arch platform plays a role of transmission hub and plays a key role in the arch structure. In this paper, the finite element analysis of the arch platform is carried out by using the large general finite element software ABAQUS 6.14. The principle and method of finite element analysis were determined, and the stress cloud map of the arch platform under the combination of 1.0, 1.35 and 2.0 times of the most unfavorable load conditions was obtained. The results show that the platform is in elastic stage under 1.0 times and 1.35 times load, and partial yield under 2.0 times load. It has good bearing capacity and safety reserve, and the design is safe and reliable.更多还原
