［摘要］依托實(shí)際工程，通過兩個(gè)鋼-混凝土組合梁與鋼筋混凝土柱連接節(jié)點(diǎn)的縮尺模型試驗(yàn)，提出了以對(duì)拉鋼筋代替鋼梁翼緣穿過節(jié)點(diǎn)核心區(qū)的梁柱節(jié)點(diǎn)做法。試驗(yàn)證明，此類節(jié)點(diǎn)構(gòu)造合理，傳力可靠，施工方便，具有良好的承載能力和抗震性能。在試驗(yàn)研究基礎(chǔ)上，提出了節(jié)點(diǎn)的抗剪承載力及構(gòu)造措施，為該類節(jié)點(diǎn)的設(shè)計(jì)與施工提供參考。

Abstract:Based on a real case, design concept and constructional details of the joints between steel-concrete composite beam and reinforced concrete column were introduced through the experiment of two models, in which steel beam flanges were substituted with reinforcement in the case design of a conference building. The test results indicate that the joint is comparatively safe and rational.Shear capacity and construction methods are also advanced which provide reference for the project design and construction.

Keywords:steel-concrete composite beam; reinforced concrete column; joint
