【摘要】 为研究巨型组合框架结构的力学性能和简化计算方法,利用结构分析QR法对其进行计算。以样条结点位移参量为基本未知量,推导出巨型组合框架结构分析的样条离散化刚度方程,通过样条结点位移求得结构节点位移和各杆件杆端内力。编制了巨型组合框架结构计算的相应程序,计算了某巨型组合框架模型在不同连接方式下的节点位移和杆端内力,并将本文计算结果与其他方法的计算结果进行对比。算例结果表明,该方法是一种经济有效且可靠的结构分析计算方法,可应用于半刚性连接巨型组合框架结构及类似结构。在进行巨型组合框架结构设计时,应当考虑半刚性连接对结构力学性能的影响。更多还原

【Abstract】 To study the mechanical properties and simplified computational method of mega composite structures,QR method for structural analysis was used to calculate these structures.With the displacement parameters of spline nodes chosen as the basic unknown variables,the stiffness equation for spline discretization of mega composite frame structures was deduced.The joint displacements and internal forces in all bars were determined by the displacements of the spline nodes.The corresponding procedure for computing the mega composite frame structure was compiled,and then the joint displacements and internal forces in elements of one mega composite frame under different connections were computed.All the results were compared with those of the Finite-Element software and relational references.Results show that the method is an economical,effective and reliable method for structural analysis.It is applied to computing the mega composite frame structures with semi-rigid connections and other similar structures.The impact of semi-rigid connections to the mechanical properties should be considered while designing mega composite frame structure.更多还原
