    摘要:

    托换节点的可靠性是保证房屋整体平移安全的重要因素之一. 为研究砖柱托换节点在平移过程中的受力性能,以某保护建筑为例,采用ABAQUS有限元软件建立了平移工程中砖柱托换节点的有限元模型,分别对采用高性能水泥复合砂浆钢筋网(HPFL)加固的托换节点和未加固的托换节点的受力和变形性能进行分析,同时结合现场监测数据对有限元结果进行对比分析. 结果表明,采用HPFL加固方式能有效提高砖柱托换节点的承载力和变形能力,有效抵抗平移过程中各种不利作用,该加固托换方式是安全可靠的;实际监测结果与模拟结果吻合较好,证明了该模拟方法的可行性.

    Abstract:

    The reliability of the brick column underpinning joints is one of the important factors to ensure the safety of building monolithic moving. In order to study the mechanical performance of the brick column underpinning joints in the process of moving, this paper takes a protected building as an example and uses the ABAQUS finite element software to establish the finite element model of the brick column underpinning joints. Through the simulation analysis,the stress and deformation performance of high performance ferrocement laminate(HPFL) reinforced and unreinforced underpinning joints are investigated. Meanwhile, the comparison with field monitoring data are also carried out. The results show that HPFL reinforcement method can effectively improve the bearing capacity and deformation capacity of the brick columns underpinning joints,and the ability of effective resistance under various adverse effects in the process of translation is also proved. The method is safe and reliable. The simulation results are in good agreement with the field monitoring results ,which proves the feasibility of the simulation method.
