钢筋混凝土框架柱的抗震性能

Seismic Behaviour of Columns in Reinforced Concrete Frames

本文根据97根钢筋混凝土框架柱在低周反复荷载作用下的试验研究,将其破坏形态分为弯曲型、粘结型及剪切型三大类。主要对其强度和延性进行了分析和讨论,并提出了相应的计算公式以及构造措施。

Based on the test results of 97 columns in reinforced concrete frames under cyclic loadings, this paper classifies the failure modes into three types--flexure type, bond type and shear type. Analysing the strength and the ductility of the columns, for- mulas for their calculation and the detailing of the columns are suggested.
