【摘要】：砌体结构在我国已有建筑中有着大量的应用,随着科学发展观的深入贯彻,可持续发展的理念逐渐深入人心。为了有效利用资源,建设领域内充分利用既有建筑物,开展既有建筑物的加固改造日益受到重视。目前已有一系列的加固改造措施,也已制定了《砌体结构加固设计规范》来完善这个行业。本文通过对四片砖墙在不同的加固措施下,进行低周往复荷载作用来模拟地震作用,分析实验的各种参数,以此来检验砖墙加固后的效果。在实验的基础上,使用非线性有限元软件ANSYS,对四片砖墙进行模拟计算,对理论结果与实验结果进行对比,发现理论与实验相对来说比较吻合。由此基础上分析总结了不同的加固方法对砖墙剪切变形和极限承载力的影响,主要分析X形钢筋网高强砂浆加固砖墙后的抗震性能,重点探讨X形钢筋网高强砂浆加固砖墙的各种技术指标,得出其合理、有效的结论。
[Abstract]:Masonry structure has a large number of applications in the existing buildings in our country. With the implementation of the scientific development concept, the concept of sustainable development has gradually become popular.In order to make full use of the existing buildings in the construction field, more and more attention has been paid to the reinforcement and reconstruction of the existing buildings in order to utilize the resources effectively.At present, there have been a series of reinforcement measures, and the Code of masonry structure reinforcement Design has been formulated to perfect this industry.In this paper, four brick walls are subjected to low-cycle reciprocating loads under different reinforcement measures to simulate the seismic action, and to analyze the parameters of the experiments to test the effect of the reinforced brick walls.On the basis of the experiment, four brick walls are simulated and calculated by using the nonlinear finite element software ANSYS.The theoretical results are compared with the experimental results, and it is found that the theory is in good agreement with the experimental results.Based on this, the influence of different reinforcement methods on shear deformation and ultimate bearing capacity of brick wall is analyzed, and the seismic behavior of brick wall strengthened with high strength mortar with X-shaped steel mesh is analyzed.Various technical indexes of strengthening brick wall with high strength mortar with X-shaped steel mesh are discussed emphatically, and the reasonable and effective conclusions are obtained.
