[摘要]根據鋼筋混凝土柱-鋼梁(RCS)組合節(jié)點的破壞模式,分析了節(jié)點的受力機理。RCS組合節(jié)點的傳力機構大致分為四種:鋼梁腹板框架-剪力墻機構、內部混凝土斜壓機構、外部混凝土斜壓機構及桁架機構,同時分析各傳力機構能夠承擔的抗剪承載力貢獻值。根據國內外研究資料,考慮節(jié)點區(qū)混凝土受力機理不同,重點介紹了RCS組合節(jié)點抗剪承載力公式的研究進展,為后續(xù)RCS組合節(jié)點抗剪承載力研究提供參考。

Abstract:Based on the failure modes of reinforced concrete column-steel beam(RCS) composite joints, the force mechanism of the joint was analyzed. Force transferring mechanisms of RCS composite joints are divided into four categories, including steel beam web prame-shear wall mechanism, internal concrete inclined compression mechanism, external concrete inclined compression mechanism and truss mechanism. The contribution of each force transferring mechanism to the shear capacity was analyzed. According to the domestic and foreign research data, taking into consideration of different force mechanisms of concrete in node regions, the research progress of shear bearing capacity formula of RCS composite joints was focused on, providing reference for subsequent study on shear bearing capacity of RCS composite joints.
Keywords:reinforced concrete column\|steel beam (RCS); composite joint; failure mode; force transferring mechanism; shear capacity
