采用杆系模型形成结构的总刚矩阵,分析时考虑了梁、柱的弯曲、剪切、轴向变形以及节点域的剪切变形;经过静力缩聚将其化为质点串模型,然后结合层模型的一些特点,得出等效层间剪切刚度,最后利用层间剪切模型的简化二阶分析方法得到了考虑二阶效应及节点剪切变形的层间剪切模型总刚矩阵。
Although methods for the second-order effects of plane frames were developed in the 1980s, much of this early work was surprisingly sophisticated or simplified and, it is worth re-visiting.
采用共旋坐标法准确地导出了平面梁单元发生大转动小应变时的单元切线刚度矩阵,并利用该单元切线刚度矩阵的列式和Newton-Raphson迭代法开发了1个FORTRAN程序NPFSAP,从而获得了高层框架结构二阶效应的高精度数值解,由此发现高层建筑的二次效应与水平荷载的关系不明显,但建筑物刚度越小,竖向荷载越大,建筑物层数越多,二次效应越明显提出了1个高层框架中柱二次效应的计算公式,为工程设计人员提供了准确计算框架弯矩的办法。
