在某超高层钢结构施工过程中,从工程实际出发,深度理解结构设计特点,安装上减少约束、增加临时固定措施,在焊接顺序和焊接工艺方面降低应力和应变,同时与测量紧密配合,从而降低施工累计误差;采取预调控制量抵减构件钢柱压缩和混凝土徐变,进一步提高钢结构安装精度;最后结合本工程实例,指出建模模拟的局限性,提出待解决的问题。
In a super high-rise steel structure construction process, starting from the actual project, the depth of understanding of structural design features, reduce the constraints on the installation to increase the temporary fixed measures in the welding sequence and welding process to reduce stress and strain, and measurement and work closely with Reduce the cumulative error of construction; take precontrolled control amount to reduce the compression of steel columns and concrete creep to further improve the precision of steel structure installation; Finally, combined with the project example, pointed out the limitations of modeling and simulation, and proposed the problems to be solved.
