摘　　要：已有研究中很少有将粗骨料的粒径作为钢筋混凝土板冲切强度计算公式影响参数的案例.钢筋混凝土板的抗剪效果不仅受抗拉侧钢筋限制,还与抗压侧钢筋量相关,容易发生负弯矩的板其抗压侧配筋量很大.因此,利用骨料粒径及抗压侧配筋量不同的10个板试件的实验结果,分析骨料粒径和抗压侧配筋量对钢筋混凝土板冲切强度的影响,并对钢筋混凝土板冲切强度的中国规范计算公式进行探讨.There are nearly no case to take the thick aggregate particle size as a reinforced concrete slab punching shear strength calculation formula in the past research.Meanwhile,the reinforced concrete plate shear effect is not only limited to lateral tensile reinforcement,but also is related to lateral compressive reinforcement.Also,it is easy for the bending plate of the lateral compressive to have large reinforcement quantity.Therefore,text results of aggregate size and lateral compressive reinforcement quantity concerning with 10 different plate specimen is used to analyze aggregate size and lateral compressive reinforcement quantity’s influence on punching shear strength of reinforced concrete plate,and a discussion about Chinese concrete code formula which are connected with the reinforced concrete plate punching shear strength is made.
