構造安全性と生産合理性の融合を目指した鉄筋コンクリート造事務所ビル建築に関する研究その5: 大スパン構面の柱梁接合部部分架構の実験結果の検討

摘要

From the test results, following conclusions can be drawn.1) The shear bracket worked well and succeeded to transfer the shear force from the beam to the column, and minimized the slip of the beam, excluding the specimen SP3.2) Except specimens SP3, other specimens successfully exceeded the target story drift of 4%. No decay of the strength was observed, with the exception of in the positive direction of the specimen SP4. Few cracks were recorded, especially in the column and joint, especially in specimens which the shear bracket was applied.3) The vertical slip of the beam was much larger in the specimen without shear bracket (SP1), and significantly reduced in the specimens with shear bracket. The friction coefficient of 0.5 was not satisfied and smaller value should be used.
