［摘要］青島萬邦中心1#樓高度232.4m，采用鋼-混凝土混合結(jié)構(gòu)，整體體系為斜撐框架-核心筒結(jié)構(gòu)，平面形狀不規(guī)則，各角柱位置均采用異形型鋼混凝土柱——魚鉤形型鋼混凝土柱，含鋼率大于15%，屬于高含鋼率型鋼混凝土柱。試驗(yàn)采用兩個(gè)1∶6縮尺魚鉤形型鋼混凝土柱模型，含鋼率為16.8%，分別采用小偏心和軸心受壓加載方式進(jìn)行試驗(yàn)，得到了型鋼柱承載力與破壞形式。試驗(yàn)結(jié)果表明，異形型鋼混凝土柱的破壞屬于延性，而型鋼的性能對于試件整體延性具有決定性作用。

Abstract:The building 1# of Qsingdao Wanbang Center is 232.4 meters high, which is steel-concrete composite structure. The system is composite brace-frame and core wall structure. Because of the irregular plan, the corner columns are especial shaped steel reinforced concrete column, which looks like a fishhook. The percentage of steel in the columns is very high up to more than 15%. Two models of steel reinforced concrete column on scale 1∶6 in which percentage of steel is up to 16.8% were tested in the experiment. The experiment contains two test modes-axial compressive mode and small eccentric compressive mode. The experimental results indicate that it is ductile fracture of the especial shaped steel reinforced concrete column, and the performance of the steel determines the whole ductile performance of the model.
Keywords:especial shaped steel reinforced concrete column；experimental research； steel-concrete composite structure
