【摘要】 根据钢筋混凝土框架柱受震破坏的各种常见现象,从内容组织结构入手,研究分析了钢筋混凝土柱受力变形过程,揭示了它的破坏机理及相应强度的变化规律,认为应当加强在复杂应力状态以及循环加载过程中钢筋混凝土柱的抗剪能力的实验研究,以便更好地发挥钢筋混凝土柱的钢筋和混凝土的共同作用,提高构件与结构的延性。更多还原

【Abstract】 The paper studies various kinds of damage styles of R.C.frame columns under earthquake from inner organization and distortion procedure under loads,and reveals its damage mechanism and corresponding strength variation rule.It is shown that test researches on shear resistance capacity of R.C.columns under complicated stress state and cycle loads are needed,for better use of concrete and steel bars by improving its ductility.更多还原
