［摘要］由于建筑方案需要，大連國(guó)際會(huì)議中心工程中設(shè)計(jì)了一批鋼管混凝土斜折柱，斜折柱下部豎直，中部開始彎折，且折角較大，其上部為支撐鋼平臺(tái)，斜折柱受力狀態(tài)復(fù)雜。通過試驗(yàn)，對(duì)斜折柱的極限承載力、延性、剛度等力學(xué)性能進(jìn)行了研究。研究表明，斜折柱上下柱折角處應(yīng)力集中現(xiàn)象明顯。采用加厚折角處鋼板厚度、增加縱肋、折角處采用整板連接等措施可提高斜折柱承載能力，滿足工程需要。
［關(guān)鍵詞］鋼管混凝土斜折柱；夾支支座；縮尺模型；破壞特征

Abstract:A number of the concrete filled steel tubular inclined columns are adopted in Dalian International Conference Center. The lower part of the inclined column is upright, the central part is bending, and its angle is large. The upper part supports the steel platform. The indined column is in a complex stress state. The ultimate bearing capacity, ductility, stiffness and other mechanical properties have been studied through the experiment. Studies have shown that stress concentration is obvious under the column angled inclined fold columns. Using plates with more thickness, increasing longitudinal ribs and using entire board at the connections at bending angles and other measures can improve the carrying capacity of the columns and meet the project needs.
Keywords:concrete filled steel tubular inclined column; clamped bearing; scale model;  failure characteristic
