摘 要:通过叠合板脱模、吊装荷载的理论计算,建立了有限元模型,利用理论计算验证了有限元模型的正确性,得到基于共节点模型以对叠合板进行较真实的仿真模拟。讨论了吊绳、节间、悬挑长度、板宽及吊环等影响叠合板吊装的主要因素,在最不利工况下分析了各因素对叠合板受力性能的影响。
Abstract: Through the theoretical calculation of the demoulding and hoisting load of composite slab, the finite element model is established. The correctness of the finite element model is verified by the theoretical calculation. The model based on the common node can simulate the composite slab more realistically. The main factors that affect the hoisting of the composite slab, such as the lifting rope, the internode, the cantilever length, the width of slab and the hoisting lug are discussed. Under the most unfavorable condition, the influence of various factors on the mechanical properties of composite slabs is analyzed.
