E钢筋的使用范围讲解!

添加时间:2019-03-27      发布人:

带E钢筋的适用范围,对于带E钢筋,也内人士并不陌生,抗震等级一、二、三级的框架和斜撑构件梯段,其纵向受力钢筋采用普通钢筋时,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。钢筋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,钢筋在最大拉力下的总伸长率实测值不应该小于9%。满足了此三个指标的钢筋牌号是带E钢筋,其他钢筋不太可能满足此条件也是要经过试验确定的。
  The scope of application of reinforced bar with E is not unfamiliar to the people in this field. When ordinary steel bar is used in frame and brace members with first, second and third aseismic grades, the ratio of the measured tensile strength to the measured yield strength should not be less than 1.25. The ratio of the measured yield strength to the standard yield strength should not be greater than 1.30, and the total elongation should not be less than 9% under the maximum tensile force. The grade of reinforcing bars that meet these three criteria is with E reinforcing bars, and other reinforcing bars are unlikely to meet this condition.
  具体的了解一下带E钢筋的适用范围。一方面,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。二、是框架,含框架结构中的框架,具体包括框架柱和框支柱、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。
  Specific understanding of the scope of application with E reinforcement. On the one hand, for buildings with seismic grade 1, 2 and 3, buildings with seismic grade 4 and non-seismic buildings do not need to use steel bars with E. 2. Frames, including frame columns and frame columns, frame beams and slab-column-seismic wall columns, excluding non-frame beams, floor slabs and frame beams coded KL in shear wall structures. Other structural types such as shear wall structure and brick-concrete structure do not need E reinforcement.
  三、上述框架构件的纵向钢筋,箍筋和其他钢筋也是不需要带E钢筋的。
  3. The longitudinal reinforcement, stirrups and other reinforcements of the above-mentioned frame members do not need E reinforcement.

  四、上述的三项同时满足材需要带E钢筋,只满足其中一项或者两项的不需要带E钢筋,像是四级抗震的框架、二级抗震的剪力墙、三级抗震框架柱中的箍筋等都是不需要带E钢筋,除此之外,抗震等级一、二、三的建筑伸臂衍架的斜撑、楼梯的梯段需要带E钢筋。
  Fourthly, the above three items meet the need of material with E reinforcement at the same time, only one or two of them do not need E reinforcement, such as four-level aseismic frame, two-level aseismic shear wall, stirrups in three-level aseismic frame columns and so on, all do not need E reinforcement. In addition, the skew braces of the extensional derivatives of buildings with aseismic grade 1, 2 and 3, staircase sections need E reinforcement.
  规范使用带E钢筋是有约定条件的,不是所有的抗震建筑都需要带E钢筋。以上就是关于带E钢筋的适用范围整理的相关资料,也希望对业内人士有所帮助,后期将完善此方面的知识,还望业内人士多多关注本网站,多多给予指正。
  It is stipulated that the standard use of E-reinforced bar is conditional. Not all aseismic buildings need E-reinforced bar. Above is the relevant inion about the scope of application of E-reinforced bar collation, but also hope to help the industry, the latter will improve this knowledge, but also hope that industry people pay more attention to this website, give more corrections.
