摘要
为研究门式拱架轻型房屋钢结构在静力荷载作用下平面内的受力性能和变形特性,对一榀跨度10m门式拱架进行静力加载试验。同时利用有限元计算软件AN SY S对试验模型以及与试验模型相同跨度、跨高比和截面尺寸的门式刚架进行计算。通过试验与计算结果比较分析可以看出,在结构荷载、几何条件相同的情况下,门式拱架较门式刚架具有更好的整体刚度,有利于充分地利用材料强度,提高刚架的承载能力和减少变形。
The load capacity and deformation of a 10-m spanned gabled arch steel frame were measured with static loading conditions. The test model and another model with the same span, span-height ratio, and sectional dimensions were analyzed using the finite element analysis software ANSYS. The results show that the gabled arch steel frame has better integral stiffness for the same loads and geometric conditions than standard arches. Gabled arch steel frames make better use of the material strength to increase the loading capacities and reduce the deformations.
