摘　　要：在集中荷载作用下，通过２５块钢筋砼单向板的试验，研究了板中不同配筋率、板的支承条件、不同的宽跨比对板的变形、强度和双向应力状态的影响。试验结果表明，过少的分布钢筋将使板的裂缝宽度加大。并建议，当板的宽跨比大于１．５时，分布钢筋应不少于主筋的３５％；其它情况下，分布钢筋不应少于主筋的１５％。Under concentrated load the deformation, strength and two-way stress state of 25 RC slabs are tested,which are influenced by the values of distributing reinforcement,supported form and the ratio of slab width and span(B/L ).According to the test results,ifthe value Of distributing reinforcement is lower, the width of crack in slab is wider.So, it is suggested that when B/L>1.5,the value of distributing reinforcement is not less than 35% of longitudinal reinforcenment,when B/L≤1.5,that is not less than 15%.
