摘要
选取直径均为30 m的空间钢管桁架与辐射梁水平支撑结构作对比,对两个模型分别施加0,800,1 600,2 400 k N的荷载,通过ANSYS有限元软件分析不同荷载作用下的两种结构体系,结果表明:两个有限元模型的位移都随着荷载的增大而增大,在相同荷载作用下,辐射梁支撑体系与空间钢管桁架竖向位移相差不大。杆件受力在弹性范围时,两种结构体系的最大竖向位移随荷载呈明显的线性关系。钢管桁架支撑体系比辐射梁支撑体系承受荷载能力更好。
The spatial steel pipe truss and radiation beam horizontal supporting structures with the same diameter of 30 m were selected for comparison, the two models were applied with 0, 800, 1 600, 2 400 kN loads and analyzed by the ANSYS software under different loads.The results showed that the displacement of the two finite models as the load increased.Under the same load, vertical displacement of the radiation beam support system and the spatial steel truss was not so far different.With the rod force in the elastic range, the maximum vertical displacement of two structure systems displayed a significant linear relationship as the load changed.Hence, the steel truss support system had a higher ability to withstand the load than the radiation beam support system.
