以某超高层建筑为例,对Z型和V型两种典型的伸臂桁架进行多种安装方案分析,研究单个伸臂桁架的附加内力发展规律及不同安装时序的不同影响,然后对伸臂桁架安装过程进行模拟分析和研究,验证安装时序确定方法的可靠性。相关控制分析方法可用于同类超高层结构伸臂桁架合理连接时序的确定和改进,从而指导施工过程。
Taking a super high-rise building as an example, a variety of installation schemes of Z-type and V-type cantilevered truss are studied. The development of additional internal force of single-boom truss and the different influences of different installation timings are studied. Truss installation process simulation analysis and research to verify the installation sequence to determine the reliability of the method. The relevant control analysis method can be used to determine and improve the timing of rational connection of the boom of the same kind of high-rise structure, so as to guide the construction process.
