钢筋抗拉强度、屈服强度结果修约规定是怎样的？结果保留0、5、10... [复制链接]

我们是认为这样取舍按照0   5  10是5的倍数，取舍就按照0.5倍值界限，大于2.5就升小于就舍。但是如果刚好在中间就不知道了，比如372.5。F¶¨‡ ]Ï}ëbbs.3c3t.comþ¿Û}R(µ s
所以请知道的朋友帮忙解答下，我也学学。F¶¨‡ ]Ï}ëbbs.3c3t.comþ¿Û}R(µ s

二楼的是简化的方法，比较实用，它跟三楼的方法其实是一样的F¶¨‡ ]Ï}ëbbs.3c3t.comþ¿Û}R(µ s

不懂？？？？？？？？？？？？？？？？？F¶¨‡ ]Ï}ëbbs.3c3t.comþ¿Û}R(µ s

二楼的方法很实用F¶¨‡ ]Ï}ëbbs.3c3t.comþ¿Û}R(µ s

简单的说就是：1.   ≤2.5尾数为0；F¶¨‡ ]Ï}ëbbs.3c3t.comþ¿Û}R(µ s
              2.   2.5～7.5尾数为5；F¶¨‡ ]Ï}ëbbs.3c3t.comþ¿Û}R(µ s
              3.   ≥7.5尾数为10，其实尾数也是0.就是10进一位啦！F¶¨‡ ]Ï}ëbbs.3c3t.comþ¿Û}R(µ s
