摘要
安哥拉卡宾达大学综合楼主体结构上部为2个分离式碗形结构,高低错落并呈正反相对。其高碗部采用钢结构,主体高度38.85m,由14根落地钢管混凝土柱和钢筋混凝土矩形核心筒竖向支撑构成,最大悬挑长度为23.5m。对综合楼高碗部大跨悬挑钢结构异形结构安装过程中的精度控制、超大悬挑结构安装控制、施工安全以及卸载控制技术等几方面进行了分析总结。
The upper structure of comprehensive building main structure in Angola Cabinda University has two separated bowl-type structure with high and low level and is relatively positive and negative. The higher bowl is made of steel structure, whose body height is 38.85m, supported by 14 concrete filled steel tube columns and reinforced concrete rectangular core tube, and the maximum cantilever length is 23.5m. The precision control during installation of the special-shaped structure of high bowl-type largespan cantilever steel structure, the installation control, construction safety and unloading control technology are analyzed and summarized.
