| 摘 要： | 总结了目前多高层钢框架结构计算方法存在的问题。将布莱希(Bleich，F．)建立的考虑残余应力的切线模量概念加以运用，在考虑剪切变形之后，对Liew，J．Y．R．提出的二阶精细化塑性铰法进行修正，进而建立以二阶非弹性分析为基础的基于结构极限承载力的钢框架结构分析方法。

| Abstract: | The existing problems in calculation approach for multi-story and high-rise steel frame structure are summarized. As the shearing deformation is considered, the analysis methods for steel frame structure are put forward based on the structural ultimate bearing capacity, which is on the basis of second order inelasticity analysis for steel structure. In the approach, the tangent module brought forward by Bleich, F. is used, the second-order refined plastic hinge method presented by Liew, J. Y. R. is modified. |
