网架结构不同设计软件静力性能对比分析

Static performance analysis of truss structure with different design softwares

以计算跨度为54 m的双向平板网架为例,分别运用TWCAD和3D3S软件,并结合国际通用的有限元软件ANSYS分析了每边1个铰接至每边全铰接下结构的最大挠度和最大轴力,提出了结构最合理的支座布置数目和最优边界布置形式,同时对比了各种软件的计算差异,以达到节约成本及增加结构空间的目的。

Taked two-way slab of frame with 54 m span for instance, combined with the general finite element software ANSYS in the world, both TWCAD and 3D3S softwares were used to compare maximum deflection and maximum axial force of each side of a hinged tO each side fully hinged, this article put forward the optimal boundary arrangement and the most reasonable bearing arrangement number under different boundary conditions. At the same time, it compares the calculation difference of various softwares, to achieve the purpose of cost savings and increasing the space of structures.
