你要问的是怎么查表 查钢筋锚固长度。。而不是怎么计算。。。查表查的是基本的锚固标准要求。。。如果是计算的话。。你要根据建筑结构实际情况才能知道锚固多少,怎么锚固。。。范围太广了。。。就你刚才追问的实际问题。你给的条件是:直径25 C30砼 抗震三级 根据03图集34页参照可查到 三级钢HRB400(普通钢筋)锚固长度为37d 即就是37×25(自己计算) RRB400为四级钢。。再跟你讲下钢筋等级:hpb235是1级钢筋,材料为q235,抗拉屈服强度是235n/mm2

hrb335是2级钢筋,材料为20mnsi,抗拉屈服强度是335n/mm2

hrb400是3级钢筋,材料为20mnsiv、20mnsinb、20mnti,抗拉屈服强度是400n/mm2

rrb400是4级钢筋,材料为k20mnsi,抗拉屈服强度是400n/mm2

钢筋锚固长度的计算方法是根据砼的强度及建筑抗震等级来实的,楼主请看图 回答人的补充 :比如20厘的钢筋,抗震等级为三级,对应上表锚固长度就是31倍钢筋直径,也就31*20=620MM

找本建筑构造的书学学,内容比较多。
