摘要
对某行政楼61m跨"飘带"状网架和56m跨K形桁架整体吊装施工方案进行分析,采用有限元软件MIDAS分别对网架和桁架的同步吊装、不同步吊装、风荷载作用和卸载整个施工过程进行数值模拟研究和挠度监测。研究结果表明,网架和桁架杆件应力与吊点位移均满足要求,说明整体吊装施工方案可行。
The hoisting construction methods of an administration building with 67 m span streamer-shape girds and 56 m K-type truss structures are analyzed. Finite element software MIDAS is used to make numerical simulation and displace monitoring on girds and trusses under the whole construction process about synchronous hoisting,not synchronous hoisting,wind load and unload step. The calculation results show that bars stress and hoisting points of girds and truss meet the requirement,which means the integral hoisting construction methods is feasible.
