摘要
梁柱体系协同作用对轮辐式张拉结构的设计分析、施工质量控制具有重要影响.介绍了考虑梁柱体系协同作用的轮辐式张拉结构分析的两个方面:协同找形分析和协同预应力分析,给出了相关控制方程.协同找形分析时索杆体系由力密度控制,不赋予材料属性,梁柱体系采用弹性模型;协同预应力分析时所有构件均采用弹性模型.以枣庄体育场为例,采用数值模拟方法对比了协同分析和非协同分析的差异.
Synergistic effect of column-beam system is important for the analysis and construction quality control of spoke structures.Two respects of synergistic analysis method of spoke structures,synergistic form-finding analysis and synergistic pre-stress analysis,were introduced respectively.In the synergistic form-finding analysis,the cable-strut system was dependent on the force density while the column-beam system was dependent on an elastic model.In the synergistic pre-stress analysis,however,the whole structure was dependent on the elastic model.The governing equations were presented as well.Based on the analysis result,numerical analysis was exemplified for Zaozhuang Stadium,and the influence of synergistic effect on structural behavior was investigated.
