摘要

摘要: 针对某超高层工程施工特点,设计了一座大型钢栈桥,栈桥大柱距处布置复杂形式支撑,支撑平面内加设吊杆与柱相连,平面外布置水平连接杆及斜平面内的支杆,保证了支撑的稳定性。利用Midas GenVer.780软件对其进行验算分析,梁的最大应力为112.7 MPa,最大变形为14.3 mm,计算结果显示结构安全可靠。施工过程中反馈的监测数据显示,梁的最大应力为99.2 MPa,最大变形为12.2 mm,结构实际应力与变形比软件模拟计算中小,主要是忽略了加劲板的作用以及最不利荷载组合的效果比实际荷载使用时偏大等原因。

Abstract: For a high-rise building, a large steel trestle was designed, complex support between the column spacing was erected; connect boom connecting with column at the support plane was set, horizontal connecting rod and inclined plane pole were also set to ensure the stability of support.Midas Gen Ver.780 software was used to check and analyze the trestle, the result was that the maximum beam stress was 112.7 MPa, the maximum deformation was 14.3 mm, which showed that the steel trestle structure was safe and reliable.The monitoring data during construction showed that the maximum beam stress was 99.2 MPa, the maximum deformation was 12.2 mm, Actual stress and deformation were smaller than the software simulation, mostly because the role of the stiffening plate was ignored and the most unfavorable load combination effects were larger than the actual load etc．
