摘要
广州PZB1401项目塔楼东、西两侧采用大悬挑钢结构实现整个建筑在空间上层次变幻的设计意图。采用MIDAS/Gen软件按照拟定的安装方案及施工工艺对悬挑结构进行了施工模拟分析,根据分析结果最终确定了钢结构安装顺序并对预高抛值提供了理论依据,有效保证了施工阶段的安全和施工质量。
Large cantilever steel structure on both east and west sides is adopted in Guangzhou PZB1401 project, which realizes the design intent upon the variety and gradation of architecture space. To ensure the feasibility of the construction method, prior to the installation of the large steel structures, computer simulation analysis using software MIDAS/Gen is adopted according to the construction method for the large cantilever steel structure, which provides the theoretic basis and helps in determining the installation sequence of steel structure and pre-raising height for deflection, ensures the safety and construction quality.
