柱RC・梁Sとする柱梁接合部の内部パネルのせん断破壊性状

抄録

To clarify the shear behavior of the inner panel for RCS system, twelve specimens were tested under monotonic loading. The experimental variables were the thickness of the face bearing plate, the length of loading region and so on. From the test results, it was shown that ultimate shear strength was affected by the thickness of the face bearing plate and the steel flange. An analytical model of the inner panel failing in shear was proposed. This model was composed of two elements, that is, web panel and concrete panel surrounded by the face bearing plate and the steel flange.
Based on this model, analytical formulae were proposed. It was shown that the predictions were in good agreement with the test results.
