The long period cyclic tests of four specimens near to sufficient dimension made by the master cao yunfeng prove that the reinforcement arrangement scheme can obtain favorable displacement ductility and plastic energy dissipation capacity for the coupling beams with the small aspect ratio of 1. 0. to go deep into the research further, this thesis concentrates on the two aspects following : ( 1 ) the author of this thesis carries out the long period cyclic test of five specimens near to sufficient dimension to further verify : 1 ) the probability that the upper limit of shear - resistant ability increases to vu = 0. 2fcbh0 or higher
0的位移延性，且耗能能力良好:在跨高比為0 . 8一1 . 25的范圍內，連梁都依然保持上述良好性能;配筋比例應以對角斜筋為主，一組「 l 」形斜筋用量與單向對角斜筋用量的比值宜控制在0 . 35一0 . 55的范圍內;通過對曹雲峰的試驗與本文試驗的綜合分析，表明cz于c45的混凝土強度等級都是可用的，未發現混凝土強度在這一范圍內偏高或偏低時可能帶來什麼不利影響。 -
