【摘要】 销接钢结构的销孔间隙会使结构产生初始几何位移。考虑结构平面内初始几何位移对销接结构稳定承载力的影响 ,提出了折减刚度的概念 ,并将其应用于销接结构的稳定性分析。在算例中对六四式军用梁标准三角拼组墩不考虑初始几何位移的稳定承载力、考虑初始几何位移的强度承载力和考虑初始几何位移的稳定承载力进行了比较 ,并给出了该结构考虑稳定时的临界高度。更多还原

【Abstract】 The interstice between pin and pinhole makes pin connected steel structure generate initial geometric displacement In this paper, introducing a concept of reducing rigidity, the stability bearing capacity of pin connected steel structure is studied Finally, as an example, the critical height of the column assembled by "64 Type" beam with buckling load is obtained更多还原
