as是什么意思?

as——正截面上所有纵向受拉钢筋的合力点至截面受拉边缘的竖向距离。

as=保护层厚度+箍筋直径+纵筋直径的一半。

如果近似地算,可以认为第二排钢筋的中心到截面边缘的距离就是as;如果要精确计算,用每根钢筋面积与其中心到截面边缘距离乘积的和除以钢筋总面积。工程上一般用近似算法,误差很小,而且偏于安全。

扩展资料:

假设双排钢筋间距为s,混凝土保护层厚度为c,纵向钢筋直径为d,箍筋直径为d1,梁高(或者板厚)为h,截面的有效高度h0计算如下:

对于梁 h0=h-(c+d/2+d1) (一排钢筋)

h0=h-(c+d+s/2+d1) (两排钢筋)

对于板 h0=h-(c+d/2)
