超高大跨重型钢连廊整体提升技术研究
Research on the overall lifting technology of super tall and large-span heavy-duty steel corridor
摘要
Abstract
Taking the Jinan Guohui Science and Technology Innovation Center Project as a case study,this paper addresses the key engineering challenges of steel corridors,including large lifting height,long span,and significant self-weight.A construction scheme combining in-situ assembly on the podium roof,overall hydraulic lifting,and high-altitude member implementation was proposed.Finite element analysis was conducted to simulate the lifting structure and hoisting nodes,and the numerical results were compared with on-site monitoring data.The results show that the application of overall lifting technology effectively improves construction safety.Under asynchronous lifting conditions,the diagonal bracing members experience relatively high stress,and a lifting synchrony of 20 mm at any lifting point results in an 11%increase in stress.When the height difference between the highest and lowest lifting points reaches 50 mm,the maximum stress in the corridor corridor members attains approximately 80%of the material yield strength,indicating that the spatial posture of the corridor must be strictly controlled during lifting.The measured results are in good agreement with the numerical simulations,demonstrating the reliability of the finite element analysis method.The combined use of numerical simulation and field monitoring provides effective guidance for construction and ensures the safe and smooth lifting of the steel corridor.关键词
