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14: 大スパン構面改良型の柱梁接合部部分架構の実験結果の検討

摘要

Following conclusions was drawn from the experimental resultsof this study:1) Modified shear bracket and beam socket worked well totransfer the shear force from the beam to the column, as well assatisfy the deformability of the beam at high level of drift.2) The specimens with shear bracket expressed very goodseismic performance, with small residual deformation, fullydeveloped strength, nearly no beam slip and small deformationof the beam and column element, even in very long span frame.It is high possibility to apply this type of connection in realprecast building structures.3) The specimens without shear bracket experienced large beamslip and residual drift. The slip occurred at the frictioncoefficient of 0.45, smaller than design value of 0.5.Performance of the system without bracket was inferiorcompares to the system with shear bracket.
