基于APDL参数化建模的结构吊装工程吊点布置优化

The Optimization of Lifting Points in Structural Hoisting Engineering Based on APDL Parametric Modeling

摘要: 吊点的确定是结构整体吊装工程中的一项关键性技术问题，合理的吊点布置是桁架吊装能够安全顺利进行的重要保障。外界环境、起重设备的起重能力、结构本身的结构形式以及工程实际经济条件等因素都会对吊点的确定产生一定的影响。本文以太原水上运动中心终点塔的钢结构屋面桁架吊装工程为依托，综合考虑施工现场情况和屋面桁架的力学性能，在ANSYS参数化建模和MATLAB编程的基础上，为避免单目标优化带来的局限性，将多目标粒子群算法应用于屋面桁架的吊点优化中，实现了结构吊装方案的优化，从而达到指导施工的目的。

Abstract: The determination of the lifting points is a key technical problem in the integral hoisting projects. The reasonable lifting points arrangement is an important guarantee for smoothly lifting the truss without accident. The determination of the lifting points will be influenced by the external environment, the lifting capacity of the lifting equipment, the structural form of the structure it-self, the actual economic conditions of the project, and so on. Based on the steel structure roof truss hoisting project of the Terminal Tower of Taiyuan Water Sports Center, this paper used ANSYS parametric modeling and MATLAB programming to apply the multi-objective particle swarm optimization algorithm to the lifting points optimization of roof trusses. This avoided the limitations of single-objective optimization. Meanwhile, it considered comprehensively the con-struction site situation and the mechanical properties of the roof truss. The optimization of the structural lifting scheme was realized to guide the construction.
