摘要

摘要: 西安某超高层项目中所使用的模架体系采用液压顶升模架体系,该模架结构主要由主次桁架、钢立柱和支腿桁架组成。为保证顶升模架结构在施工过程中的结构安全,基于该液压顶升模架系统的结构整体及工作原理,采用有限元软件建立了顶升模架结构体系的有限元模型,对顶升模架系统在各工况下的应力值进行模拟,并采用应力监测系统对结构关键点在不同工况下进行了应力监测。通过对相同工况和荷载组合下顶模应力的实测值和模拟结果进行对比。分析表明:应力实测值和有限元模拟结果吻合良好,该顶模在各工况下的结构应力和变形值均满足需求,结构安全。

Abstract: The formwork system used in a super high-rise building project in Xi'an adopted a hydraulic jack-up formwork system, which was mainly composed of primary and secondary trusses, steel columns and outrigger trusses. In order to ensure the structural safety of the jack-up formwork structure in the construction process, based on the overall structure and working principle of the hydraulic jack-up formwork system, the finite element model of the jack-up formwork structure system was constructed, the stress values of the jack-up formwork system in various working conditions were simulated by FEM, the stress monitoring system was used to monitor the key points of the structure in different working conditions. In the same working condition and load combination, the measured stress of the jack-up formwork was compared with the simulation results. The results showed that the measured stress and finite element simulation results effectively verified that the structural stress and deformation of the jack-up formwork could meet the requirements in various working conditions, the structure was safe.
