摘要
在自密实混凝土加固柱的拟静力试验基础上,研究初始轴向应力水平对增大截面加固柱抗剪承载力的影响规律。同时,基于剪切粘结破坏和弯曲型破坏的的抗剪机理,分别提出抗剪承载力计算的理论公式。将理论值与试验值进行对比,验证文中提出公式的有效性。
Based on the quasi-static test of the columns strengthened by self-compacting concrete（scc）,The effect rule on RC column strengthened by SCC under different initial stress was analyzed.the shear capacity of RC column strengthened by SCC under twice-loading is simulated and analyzed,The calculation formula of shear capacity under shear adhesive failure and flexural mode failure was put forward.The calculation results coincide well with the test results.
