EXPERIMENTAL AND BEARING CAPCITY STUDIES ON THE SEISMIC BEHAVIOR OF UNREINFORCED MASONRY WALLS STRENGTHENED WITH HDC LAYERS

  • 摘要: 为研究高延性混凝土(HDC)加固无筋砖墙的抗震性能,设计制作了3片HDC面层加固砖墙、1片钢筋网水泥砂浆面层加固砖墙和1片作为对比试件的未加固砖墙,通过拟静力试验,研究了HDC面层加固砖墙的破坏形态、滞回性能及耗能能力。试验结果表明:HDC面层可对墙体形成约束作用,延缓墙体开裂并改变墙体的破坏模式,提高墙体的承载力和延性;与钢筋网水泥砂浆面层加固相比,单面HDC加固的墙体开裂荷载与耗能能力明显提高,承载力下降缓慢。针对试件的破坏形态,考虑未开裂区加固面层对墙体水平承载力的贡献,提出了加固墙体的承载力计算方法,并根据试验结果进行了验证。
    Abstract: To investigate the seismic behavior of unreinforced masonry walls strengthened with high ductile concrete (HDC) layers, three brick masonry walls strengthened with HDC layers, one brick masonry wall strengthened with steel-meshed cement mortar, and one brick masonry wall served as the reference specimen were designed. The failure pattern, hysteretic characteristics and energy dissipation capacity were studied through the quasi-static tests. The test results show that the HDC layers can provide a constraining effect for the wall, effectively delay the generation of cracks, change the failure mode and improve the lateral strength and ductility of the wall. After being strengthened with a single HDC layer, the cracking load and energy dissipation capacity of the wall is obviously higher than that strengthened with steel-meshed cement mortar and the bearing capacity decreases slowly. A calculation method is proposed to estimate the ultimate lateral strength of strengthened masonry walls and the accuracy of the method is validated by the test results.
