地下室顶板在重载吊车作用下承载力验算与加固技术
|
摘要
对重型汽车吊上地下室顶板进行可行性分析,应用Midas有限元计算软件辅助计算,就汽车吊行驶状态,工作状态、分别从楼板承载能力极限状态及正常使用极限状态两个方面对地下室混凝土顶板进行验算,并探索总结出一套地下室顶板加固措施,保证整个吊装过程安全可靠,确保地下室顶板主体结构在重载后完好无损。
We analyzed the feasibility of hanging the basement roof of heavy trucks, applied Midas finite element software to assist calculation, checked the concrete roof of basement from two aspects: the ultimate state of floor bearing capacity and the ultimate state of normal use, and explored and summarized a set of reinforcement measures of basement roof to ensure the safety and reliability of the whole hoisting process, and ensure that the main structure of basement roof is intact after heavy load.
