摘 要:实际工程中大截面梁的混凝土浇筑体积较大,梁下支撑的跨距和步距较小,虽然在使用过程中支撑的安全储备较大,但存在搭设支撑耗时、危险性较大且不经济等缺点。结合工程实例运用有限元软件Ansys中单元生死功能对叠合梁的浇筑进行模拟,对使用叠合梁浇筑方式下梁下支撑进行屈曲分析,并对梁下支撑系统进行了安全性和经济性优化。
Abstract: In actual project, concrete pouring volume of large section beam is large, under beam shoring scaffold span and interval are smaller, while the safety stock to shoring scaffold in use is bigger. When set-up shoring scaffold, there are shortcomings such as time consuming, risky and uneconomical. Combined with practical engineering, th finite element software Ansys is used to simulated with birth and death element in the composite beam casting, the beam buckling analysis is carried out by the use of composite beam under the shoring scaffold of the casting mode, and the safety and economic optimization of beam supporting system is also carried out.
