【摘要】 大跨度空间桁架梁体系在多高层钢结构以及混合结构中的应用日益普及,由于现行规范中对其整体稳定的计算规定并不明确,因此,有必要对它的整体稳定的影响因素进行分类分析。针对实际工程中的空间桁架梁进行基于有限元分析的模拟试验,对此类桁架梁的整体稳定承载力影响因素进行了研究,并得出一些结论。更多还原

【Abstract】 Although long-span special truss beam system is becoming more and more common in the high-rising steel structure and concrete-steel structure buildi ng s, it is still necessary to analyze the factors influencing its integer stabilit y because of th e uncertain calculation of the current codes. This paper will do some te sts on th e spatial truss beams based on the finite element theory and analyze the factors influencing the potential integer stability, then draw some conclusions.更多还原
