hrb400e和hrb500e有什么区别?e是什么意思
推荐回答（3个）
一、hrb400e和hrb500e的区别
hrb400e和hrb500e的区别主要是强度级别不同：
hrb400e：hrb400e的强度级别为400MPa。
hrb500e：hrb500e的强度级别为500MPa。
二、“e”是指类型为抗震钢筋。
hrb400e和hrb500e都是带E钢筋。带E钢筋的核心是钢筋超屈比指标不能过大，而强屈比和伸长率指标不能太小。
带E钢筋要求纵向受力钢筋检验实测最大强度值与受拉屈服强度的比值（强屈比）不小于 1.25， 使结构某部位出现较大塑性变形后，钢筋仍具有必要的强度潜力，即塑性绞处有足够的转动能力与耗能能力，为了保证构件的基本抗震承载力。
扩展资料
“hrb400e”的带E钢筋的使用范围：
1、抗震等级一、二、三的建筑，四级抗震和非抗震建筑不需要使用带E钢筋；
2、框架，含框剪结构中框架，具体包括框架柱和框架梁、框支柱、框支梁和板柱-抗震墙的柱，不包括非框架梁、楼板，也不包括剪力墙结构中的代号为KL的“框架梁”。剪力墙结构、砖混结构等其他结构类型不需要带E钢筋。
3、是上述框架构件的纵向钢筋，箍筋和其他钢筋不需要带E钢筋；
4、以上1、2、3条同时满足才需要带E钢筋，只满足其中一项或二项的不需要带E钢筋。除此之外，抗震等级一、二、三的建筑伸臂桁架的斜撑、楼梯的梯段需要带E钢筋；
5、规范对使用带E钢筋是有约定条件的，并非所有的抗震建筑都需要带E钢筋。

带e钢筋这是新规范规定的抗震钢筋。带E钢筋符号HRB400E，是指强度级别为400MPa且具有抗震性能的普通热轧带肋钢筋。带E钢筋的核心是钢筋超屈比指标不能过大，而强屈比和伸长率指标不能太大
对有抗震设防要求的结构，其纵向受力钢筋的性能应满足设计要求；当设计无具体要求时，对按一、二、三级抗震等级设计的框架和斜撑构件（含梯段）中的纵向受力钢筋应采用HRB335E、HRB400E、HRB500E、HRBF335E、HRBF400E或HRBF500E钢筋，其强度和最大力下总伸长率的实测值应符合下列规定：
1 钢筋的抗拉强度实测值与屈服强度实测值的比值不应小于1.25；(强屈比)
2 钢筋的屈服强度实测值与屈服强度标准值的比值不应大于1.30；(超强比)
3 钢筋的最大力下总伸长率不应小于9%。
屈服强度不同 HRB400E的屈服强度400MPa,HRB500E的屈服强度是500MPa。
屈服强度不同的同时抗拉强度也相应的不一样,说通俗点HRB500E的钢筋能承受的拉力更大。
后缀有E的是抗震钢筋，抗震钢筋的实验室数据对断后总伸长、强屈比和超强比有要求，说通俗点就是对抵抗地震影响会好一些
