我国混凝土结构“强柱弱梁”抗震措施合理性分析

Rationality analysis on seismic fortification measures about "strong column-weak beam" for concrete structures in China

为了保证在大震作用下框架结构的稳定性,本文借鉴欧洲规范EC8“柱-梁承载力级差系数”的取值,提出了对部分抗震等级的框架结构的柱端抗弯能力增强系数应予以提高,以降低框架柱屈服的可能性。

To guarantee the stability of the frame in strong earthquake motion, and on the basis of analysis on the coefficients by the European Prestandard Euroeode 8, it is advised that the moment amplification coefficients at the bottom sections of columns for frame structures in some seismic intensity be increased to reduce the possibility of the frame column yielding.
