| 摘 要： | 通过试验研究，提出了基于能力设计法的框架柱塑性铰区抗剪承载力计算公式，并对此进行了可靠度分析。定量分析了该计算公式的可靠指标与剪跨比、配箍率等因素的关系。同时针对目前我国现行规范抗剪承载力计算的可靠度指标偏低较多的情况，该建议公式对不同抗震要求的构件提出了不同的可靠指标，既考虑了我国设计习惯，又体现了能力设计法的要求，充分考虑了安全性的要求，对工程应用具有较大的参考价值。论文的主要研究成果已被《混凝土结构设计规范》(GB50010-2002)吸收。

| Abstract: | In China the reliability degree of the shear resistance is less safe than those in other countries. A seismic shear capacity predictive equation for ductility reinforced concrete columns based on capacity design philosophy is suggested after the shear test of 10 columns has been made. In the article, on the basis of test data collected from Japan and the test data, the reliability index of the suggested equation as to shear span ratio and transverse reinforcement is studied. The reliability index of the suggested equation is various with ductility levels, so the equation is more rational than that in Chinese Concrete Design Code (GBJ10-89). The results in the article are important to modify the Chinese concrete design code. |
