钢筋混凝土板冲切锥体比较分析研究

RESEARCH AND ANALYSIS FOR PUNCHING-SHEAR CONE OF REINFORCED CONCRETE SLABS

对钢筋混凝土无冲切筋板受冲切承载力计算及冲切计算周长um 的取值进行了比较分析 ,针对同一荷载值不同荷载作用面的冲切承载力计算中出现的不足现象 ,提出一个um 的取值方法 ,以修正不同作用面形状造成的计算结果矛盾现象。

Considering the defect on punching\|shear strength of the same load on different loading area,a method to calculate( u \-m) to modulate conflict causing by different loadings is presented in this paper.According to the comparative analysis of punching shear strength of the RC slabs without punching shear rebars and the definition of punching shear calculating circumference( u m).
