【摘要】 结构的几何刚度与应变中的某些特定非线性项相对应,与弹性刚度相比,其对一般结构计算结果的影响通常可忽略不计。但对于某些较特殊或高层建筑结构,则需要考虑其影响。本研究通过对几个工程实例的计算,表明在有些结构尤其是高层建筑结构中,几何刚度对计算结果的影响比较显著,进行梁柱效应分析是必要的。更多还原

【Abstract】 Compared with elastic stiffness, the effect of geometric stiffness which corresponds to some non-linear terms in structural strain, is relatively small and often neglected in structural analysis in most cases. However, the influence must be taken into account for some special structures. The result comparison of two engineering examples shows that the effects of geometric stiffness should not be neglected for some structures, especially for high-layer buildings. For such structures, beam-column effect analysis is necessary.更多还原
