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.

　　具體的了解一下帶E鋼筋的適用范圍。一方面，抗震等級(jí)一、二、三的建筑，四級(jí)抗震和非抗震建筑不需要使用帶E鋼筋。二、是框架，含框架結(jié)構(gòu)中的框架，具體包括框架柱和框支柱、框支梁和板柱-抗震墻的柱，不包括非框架梁、樓板、也不包括剪力墻結(jié)構(gòu)中的代號(hào)為KL的框架梁。剪力墻結(jié)構(gòu)、磚混結(jié)構(gòu)等其他結(jié)構(gòu)類型不需要帶E鋼筋。

　　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、上述框架構(gòu)件的縱向鋼筋，箍筋和其他鋼筋也是不需要帶E鋼筋的。

　　3. The longitudinal reinforcement, stirrups and other reinforcements of the above-mentioned frame members do not need E reinforcement.

　　四、上述的三項(xiàng)同時(shí)滿足材需要帶E鋼筋，只滿足其中一項(xiàng)或者兩項(xiàng)的不需要帶E鋼筋，像是四級(jí)抗震的框架、二級(jí)抗震的剪力墻、三級(jí)抗震框架柱中的箍筋等都是不需要帶E鋼筋，除此之外，抗震等級(jí)一、二、三的建筑伸臂衍架的斜撐、樓梯的梯段需要帶E鋼筋。

　　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.

　　規(guī)范使用帶E鋼筋是有約定條件的，不是所有的抗震建筑都需要帶E鋼筋。以上就是關(guān)于帶E鋼筋的適用范圍整理的相關(guān)資料，也希望對(duì)業(yè)內(nèi)人士有所幫助，后期將完善此方面的知識(shí)，還望業(yè)內(nèi)人士多多關(guān)注本網(wǎng)站，多多給予指正。

　　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 information 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.
