摘要
针对刚性楼板假定和柔性楼板假定,结合国内常用的结构设计软件ETABS、SAP2000和PKPM,通过算例对比分析,得出不同楼板假定对交错桁架整体分析结果的影响情况.研究结果表明,基于空间三维分析的刚性楼板假定能够满足交错桁架结构整体分析的精度要求.
Combined with the domestic common structure design software ETABS,SAP2000 and PKPM,an example is analyzed based on the assumption of rigid slab and flexible slab,which can be used to analyse the influence of entire structure.It is demonstrated that the assumption of three-dimensional rigid slab can satisfy the accuracy of global analysis in staggered-truss system.
