Lifting Point Optimization of Large Steel Truss on the Principle of Minimum Potential Energy

Abstract:

The integral hoisting construction technology of large steel truss has been widely used in the steel structure construction. Based on the principle of strain energy, the feasibility analysis on lifting point optimization of Wuhan public house’s large steel truss was conducted. It expounded the integral lifting construction technology of Wuhan public house’s large steel truss. Through the 12 different methods of lifting point setting and the application of finite element analysis software SAP2000, it discussed the optimization method of hoisting points of large steel truss on the principle of minimum potential energy. It achieved the change rule of the whole strain energy of steel truss. The scheme of 10 lifting points was identified on the economy and construction conditions. The stress state, the structural deformation state and the steady mode was analyzed under the optimum lifting point condition. The results meet the design and construction requirements, and this research method can provide the certain reference value for similar engineering.
