Evaluations about factor of effective concrete width of RC column- S beam joints with a cover plate in shearing capacity

Abstract

The effective concrete width of 13 beam-through type reinforced concrete column-steel beam joints with a cover plate was analyzed in this study, it was found that the factor of effective concrete width of test specimens decreased with the increase of column-to-beam width ratio when the column-to-beam ratio was less than 3.2. Based on the analysis, the factor of effective concrete width was proposed, and it was found that the shear strength of the test specimens is better agreement with test results than AIJ Recommendations for Design Mixed Structurers Composed of Reinforced Concrete Columns and Steel Beams and formula proposed by Sakaguchi Noboru.
