Proposal of shear strength formula including proportion effects of shear planes

摘要

In this research, we try to estimate shear strength including proportion effects with our proposing empirical formula of shear strength. For practical structural calculation, we made shear strength formula simple. We replaced stress concentration effects with proportion effects between width and height of a shear plane in the formula. Shear tests were examined in four methods. First tests are horizontal loading tests on beam-column joints with buried tensile bolts. Second tests are monotonic loading tests on joints with buried tensile bolts. Third tests are shear tests specified in the Japanese Industrial Standards (JIS Z2101). Fourth tests are double shear tests with parameters including the proportion of a shear plane. We proposed empirical formula of shear strength, based on results of fourth tests.
