科威特中央银行总部大楼(Central bank of Kuwait new headquarters building,简称CBK)为非规则钢筋混凝土核心筒与外侧钢框架组合而成的超高层混合体系结构。介绍了钢结构设计过程中对初步设计的一些合理补充和修改,通过计算证实了斜肋柱X节点的设计能够满足承载力要求,根据美国规范ASCE7—05的规定和风洞试验报告确定了本工程的风荷载取值。应用有限元分析软件ETABS,对不同施工方案的施工过程进行了模拟分析,以了解不同施工方案中结构构件的应力变形在施工全过程中的发展变化情况,通过比较选择较为合理的施工方案,从而确保复杂超高层建筑结构在施工过程中的安全。
The Central Bank of Kuwait new headquarters building (CBK) is a super-high-rise hybrid system consisting of an irregular reinforced concrete core tube and an outer steel frame. This paper introduces some reasonable additions and revisions to the preliminary design in the process of steel structure design. It is confirmed by calculation that the design of the X-slant column X-node can meet the requirements of bearing capacity. According to the provisions of ASCE7-05 and the wind tunnel test report, Wind load value of the project. The finite element analysis software ETABS was used to simulate the construction process of different construction schemes to understand the development and changes of the structural components in different construction schemes during the whole construction process. By comparing and selecting the more reasonable construction schemes, To ensure the safety of complex super tall building structure during construction.
