填充墙对钢筋混凝土框架整体受力-位移曲线有显著影响，并可能影响抗震性能评估的结果。因此，明确考虑它们的存在是至关重要的。在简单横向机制分析（SLaMA）框架中，一种推导填充框架结构非线性静力-位移曲线的分析方法已经在一篇论文（第1部分）中提出。在本文中，提出的程序应用于72个案例研究填充框架具有不同的几何形状（两层，四层，六层；两层，四层），钢筋混凝土构件的能力和配置，强度和填充的分布。所得的容量曲线与精细的数值推覆分析进行了比较。观察到的满意匹配证明了所提方法的准确性和可靠性。
Infill walls have significant effects on the global force–displacement curve of Reinforced Concrete (RC) frames, and possibly on the outcome of a seismic performance assessment. Therefore, it is paramount to explicitly consider their presence. An analytical procedure to derive the non-linear static force–displacement curve of infilled frame structures, within the Simple Lateral Mechanism Analysis (SLaMA) framework, has been presented in a companion paper (part 1). In this paper, the proposed procedure is applied to 72 case study infilled frames with different geometry (two, four, six stories; two, four bays), capacity and configuration of the RC members, strength and the distribution of the infills. The resulting capacity curves are compared to refined numerical pushover analyses. The observed satisfying match demonstrates the accuracy and reliability of the proposed procedure.
