提到抗震鋼筋大部分人肯定并不陌生。而抗震鋼筋的使用范圍就從字面意思上理解即是符合國(guó)家抗震要求及標(biāo)準(zhǔn)的鋼筋。在近幾年全球各地質(zhì)災(zāi)害頻繁發(fā)生，推廣使用抗震鋼筋也已經(jīng)成為人們關(guān)注的焦點(diǎn)。而只有抗震鋼筋才能在一定強(qiáng)度的地址災(zāi)害中起到保護(hù)人們財(cái)產(chǎn)安全的作用。因此，了解抗震鋼筋、使用抗震鋼筋應(yīng)該是全民共同學(xué)習(xí)的重點(diǎn)。
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.
對(duì)于有抗震設(shè)防要求的建筑結(jié)構(gòu)，其縱向受力鋼筋的性能應(yīng)當(dāng)滿足設(shè)計(jì)要求。當(dāng)設(shè)計(jì)沒有具體要求時(shí)。對(duì)按二、三、四級(jí)抗震等級(jí)設(shè)計(jì)的框架和斜撐構(gòu)件（含梯段）中的縱向受力鋼筋應(yīng)該采用HRB335、HRB400E、HRB500等鋼筋，其強(qiáng)度和最大力下總伸長(zhǎng)率的實(shí)測(cè)值應(yīng)該符合相關(guān)標(biāo)準(zhǔn)。

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、鋼筋的抗拉強(qiáng)度實(shí)測(cè)值與屈服強(qiáng)度實(shí)測(cè)值的比值不應(yīng)該小于1.25屈強(qiáng)比。
1, the ratio of the tensile strength and the yield strength of the steel bar should not be less than 1.25.
2、鋼筋的屈服強(qiáng)度實(shí)測(cè)值與屈服強(qiáng)度標(biāo)準(zhǔn)值的比值不應(yīng)該大于1.30超強(qiáng)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、鋼筋的最大力下總伸長(zhǎng)率不應(yīng)該小于9%。
3, the total elongation of steel bar under the maximum force should not be less than 9%.
從上述的描述來看，抗震鋼筋的使用范圍主要是在框架構(gòu)件和斜撐構(gòu)件的主筋中。而當(dāng)前HRB335鋼筋已經(jīng)被市場(chǎng)淘汰。取而代之最常見的抗震鋼筋是HRB400E和HRB500即三級(jí)和四級(jí)鋼筋。
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.
