【摘要】：砌體結構在我國已有建筑中有著大量的應用,隨著科學發(fā)展觀的深入貫徹,可持續(xù)發(fā)展的理念逐漸深入人心。為了有效利用資源,建設領域內充分利用既有建筑物,開展既有建筑物的加固改造日益受到重視。目前已有一系列的加固改造措施,也已制定了《砌體結構加固設計規(guī)范》來完善這個行業(yè)。本文通過對四片磚墻在不同的加固措施下,進行低周往復荷載作用來模擬地震作用,分析實驗的各種參數,以此來檢驗磚墻加固后的效果。 在實驗的基礎上,使用非線性有限元軟件ANSYS,對四片磚墻進行模擬計算,對理論結果與實驗結果進行對比,發(fā)現(xiàn)理論與實驗相對來說比較吻合。由此基礎上分析總結了不同的加固方法對磚墻剪切變形和極限承載力的影響,主要分析X形鋼筋網高強砂漿加固磚墻后的抗震性能,重點探討X形鋼筋網高強砂漿加固磚墻的各種技術指標,得出其合理、有效的結論。
[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.
