アーチ・トラスモデルに基づき主筋歪分布の解析よりRC柱の破壊モードを判別する方法

抄録

A new approach in the classification of the resulting failure mode, whether shear, bond splitting or flexure, for reinforced concrete columns is presented. Particular emphasis is placed on the analysis of the strain distribution in the main reinforcement based on the truss and arch model theory. Failure mode prediction from the proposed alternative method is compared with results from several series of column experiments. The proposed method is shown to provide a high level of precision in classifying failure modes with the proper consideration of the presence of inner rows of main bars and the effect of axial loading.
