摘要
为研究抗弯钢框架(SMRF)强震下的层剪力分布,对8个算例进行了近场地震下的时程分析。根据结构的层剪力分布曲线,提出了近场罕遇地震下SMRF平均层剪力分布模式。同前人的层剪力分布模式及时程分析结果对比表明,模式有较高的精度。
Eight moment-resisting steel frames designed for different requirements were selected to study the sto- ry shear under near-fault earthquake through nonlinear time-history analysis. The story shear distribution of each structure was obtained and a new story shear distribution pattern based on the result was proposed. The compari- son between the proposed pattern and the results obtained from the nonlinear dynamic analysis shows that the suggested distribution pattern is more rational.
