摘要
钢丝网外喷高强砂浆加固混凝土结构是一种新型结构加固方法.对4根钢丝网外喷高强砂浆加固钢筋混凝土柱和3根对比钢筋混凝土柱进行了轴压试验研究,并根据平衡方程提出了试验用的加固构件轴压极限承载力计算公式,理论计算结果与试验结果吻合的较好.研究结果表明,采用该加固方法能有效的约束柱子横向变形,并对提高钢筋混凝土柱的轴压承载力和延性有明显的效果.
Four RC columns wrapped with steel wire meshwork and subsequently strengthened by high strength mortar spray are tested respectively and compared with three control RC columns. The ultimate axial compressive strength formula of strengthening columns is also suggested according to the equilibrium equation. The test result shows that the transverse displaces of strengthened columns are restricted effectively, along with a great upgrading of both ultimate strength and ductility.
