提到抗震钢筋大部分人肯定并不陌生。而抗震钢筋的使用范围就从字面意思上理解即是符合国家抗震要求及标准的钢筋。在近几年全球各地质灾害频繁发生，推广使用抗震钢筋也已经成为人们关注的焦点。而只有抗震钢筋才能在一定强度的地址灾害中起到保护人们财产安全的作用。因此，了解抗震钢筋、使用抗震钢筋应该是全民共同学习的重点。
Most people said that the seismic reinforcement is not strange. The scope of the use of seismic reinforcement from the literal meaning is consistent with the national seismic requirements and standards of steel. In recent years, the global geological disasters occur frequently, the use of seismic reinforcement has become the focus of attention. Only the seismic reinforcement can play a role in protecting the property safety of the people in a certain intensity of address. Therefore, to understand the seismic reinforcement, the use of seismic reinforcement should be the focus of the study of the whole people.
对于有抗震设防要求的建筑结构，其纵向受力钢筋的性能应当满足设计要求。当设计没有具体要求时。对按二、三、四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该采用HRB335、HRB400E、HRB500等钢筋，其强度和最大力下总伸长率的实测值应该符合相关标准。

The performance of the longitudinal reinforced bars shall meet the design requirements of the building structure with seismic fortification requirements. When there is no specific requirements for design. In two or three, the framework of seismic grade four and the design of diagonal members (including ladder) longitudinal reinforcement should be used HRB335, HRB400E and HRB500 in the steel, should comply with the relevant standards of the measured intensity and percentage total elongation at maximum force value.
1、钢筋的抗拉强度实测值与屈服强度实测值的比值不应该小于1.25屈强比。
1, the ratio of the tensile strength and the yield strength of the steel bar should not be less than 1.25.
2、钢筋的屈服强度实测值与屈服强度标准值的比值不应该大于1.30超强比。
2, the yield strength of reinforcement and the yield strength of the standard value of the ratio should not be greater than 1.30.
3、钢筋的最大力下总伸长率不应该小于9%。
3, the total elongation of steel bar under the maximum force should not be less than 9%.
从上述的描述来看，抗震钢筋的使用范围主要是在框架构件和斜撑构件的主筋中。而当前HRB335钢筋已经被市场淘汰。取而代之最常见的抗震钢筋是HRB400E和HRB500即三级和四级钢筋。
From the above description, the use of seismic reinforcement is mainly in the frame member and the main reinforcement of the diagonal brace member. And the current HRB335 steel has been eliminated by the market. Replaced the most common seismic reinforcement is the HRB400E and HRB500 that is, three and four.
