摘要:

为研究超高层建筑顶升模架系统优化设计与现场智能化施工的数字化融合,提高材料使用效率和结构合理性,以西安某超高层建筑中所使用的顶模钢框架结构为对象,采用SIMP插值模型法,约束次桁架悬挑端竖向位移,以减少顶模钢框架结构钢材用量为目标进行优化,依据优化结果对顶模钢框架结构进行设计。应用智能建造与建筑工业化协同发展的研究成果,以拓扑优化设计、系统化安装、智能化施工为实施框架,通过拓扑优化设计结合智能化控制操作等工具,实现基于智能建造的优化型顶模钢框架结构; 系统梳理智能建造各阶段应用,利用施工管理平台,实现基于信息化模型的工程管控。结果表明:优化后顶模钢框架结构在满足约束条件情况下,在提升结构承载能力、刚度的同时,使钢框架自身重量减轻20%,降低了顶模钢框架结构用钢量,提升了钢材的使用效率,加强了拓扑优化设计与现场智能化施工的数字化融合,推动了智能化施工装备的施工应用。

Abstract:

In order to study the digital integration of the optimal design of the jacking formwork system of super high-rise buildings and the intelligent construction on site and improve the material utilization efficiency and structural rationality, taking the jacking formwork steel frame structure used in a super high-rise building in Xi'an as the object, the SIMP interpolation model method was used to constrain the vertical displacement of the cantilever end of the secondary truss, and the optimization was carried out to reduce the steel consumption of the jacking formwork steel frame structure. According to the optimization results, the jacking formwork steel frame structure was designed. The research results of the coordinated development of intelligent construction and building industrialization were applied, and the topology optimization design, systematic installation and intelligent construction were taken as the implementation framework. Through topology optimization design combined with intelligent control operation and other tools, the optimized jacking formwork steel frame structure based on intelligent construction was realized. The application of intelligent construction in various stages was systematically sorted out, and engineering management based on an information model was realized using a construction management platform. The results show that the optimized jacking formwork steel frame structure can reduce the weight of the steel frame by 20% while improving the bearing capacity and stiffness of the structure under the condition of meeting the constraints, reducing the steel consumption of the jacking formwork steel frame structure, improving the efficiency of steel use, strengthening the digital integration of topology optimization design and on-site intelligent construction, and promoting the construction application of intelligent construction equipment.
