【摘要】 青岛万邦中心1#楼高度232.4m,采用钢-混凝土混合结构,整体体系为斜撑框架-核心筒结构,平面形状不规则,各角柱位置均采用异形型钢混凝土柱——鱼钩形型钢混凝土柱,含钢率大于15%,属于高含钢率型钢混凝土柱。试验采用两个1∶6缩尺鱼钩形型钢混凝土柱模型,含钢率为16.8%,分别采用小偏心和轴心受压加载方式进行试验,得到了型钢柱承载力与破坏形式。试验结果表明,异形型钢混凝土柱的破坏属于延性,而型钢的性能对于试件整体延性具有决定性作用。更多还原

【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.更多还原
