叠合法施工过程中高位超大转换梁有限元模拟分析

Finite Element Simulation Analysis of High Position and Large Transfer Beam by Superposition-Construction

现阶段对于高位超大转换梁的研究主要集中在抗震设计方面,对于高位转换梁施工性能的研究较少。采用叠合法施工转换梁,可以减少大量模板支撑材料,降低材料的周转费用,但是叠合法施工需要考虑叠合层受力性能,因此对方案设计和施工技术要求较高。本文基于叠合法施工,采用有限元软件ABAQUS模拟分析了施工过程中模板支撑体系和楼板应力变化情况,为今后的研究提供借鉴。

At the present the study about high position and large transfer beam are mainly concentrated in the seismic design, there is little research on construction performance. It could reduce a lot of formwork support materials and construction material costs by superposition-construction transfer beam. But using superposition construcion must consider of stress performance of laminated layer. Therefore, higher requirements for the design andconstruction technology. Based on the superposition-construction, using finite element analysis software ABAQUS, construction process of formwork support system and floor stress changes were be simulated, provided a valuable reference for future research.
