The erecting bar is the steel bar in the upper part of the beam, which only plays a structural role and has no substantive significance. However, at both ends of the beam, the erecting bar in the upper part resists negative bending distance and is indispensable. (The erecting steel bar is set on both sides of the outer edge of the compression zone of the beam to fix the stirrups and form the steel bar skeleton. If the compression area is equipped with longitudinal compression steel bar, erecting steel bar can be no longer equipped. The diameter of the erecting steel bar is related to the span of the beam.

　　貫通筋是指貫穿于構件（如梁）整個長度的鋼筋，中間既不彎起也不中斷，當鋼筋過長時可以搭接或焊接，但不改變直徑

　　Penetrating bar refers to the reinforcing bar that runs through the whole length of a member (e.g. a beam) without bending or interrupting. When the reinforcing bar is too long, it can be lapped or welded without changing the diameter.

　　架立筋和貫通筋有什么區(qū)別？

　　What is the difference between erecting tendons and perforating tendons?

　　在鋼筋布置上，架立鋼筋是布置本跨的1/3，也就是說，本跨梁存在左右支座鋼筋。通長鋼筋是全長布置。架立筋起架立作用，一定的受壓作用，可以在一定程度上提高梁的承載力。

　　In the arrangement of reinforcing bars, erecting reinforcing bars are 1/3 of the span, that is to say, there are left and right support reinforcing bars in the span beam. The long reinforcement bar is the long layout. The erecting reinforcement acts as a erecting force and has a certain compressive effect, which can improve the bearing capacity of the beam to a certain extent.

　　貫通筋是指貫穿于構件（如梁）整個長度的鋼筋，中間既不彎起也不中斷，當鋼筋過長時可以搭接或焊接，但不改變直徑。貫通筋既可以是受力鋼筋，也可以是架力鋼筋。

　　The through bar refers to the reinforcing bar that runs through the whole length of a member (such as a beam) without bending or interrupting. When the reinforcing bar is too long, it can be lapped or welded without changing the diameter. The through bar can be either a force steel bar or a frame steel bar.

　　架力筋也有貫通的，如規(guī)范中規(guī)定在梁上部兩側的架力筋必須是貫通的，此時的架力筋在支座處也可承擔一部份負彎矩。

　　For example, in the code, the stiffeners on both sides of the upper part of the beam must be through. At this time, the stiffeners can also bear some negative bending moments at the support.

　　如果在梁的上下都有通長的鋼筋，一般在梁上（受壓區(qū)）且直徑較小的是架力筋，在梁下的是都受力鋼筋。

　　If there are long reinforcing bars above and below the beam, generally in the beam (compression zone) and the diameter of the smaller is the frame reinforcement, under the beam are all stressed steel bars.

　　就是負彎矩鋼筋，彎矩的定義是下部受拉為正，而梁板位置的上層鋼筋在支座位置根據(jù)受力一般為上部受拉，也就是承受負彎矩，所以叫負彎矩鋼筋。（支座有負筋,是相對而言的,一般應該是指梁的支座部位用以抵消負彎矩的鋼筋，俗稱擔擔筋。一般結構構件受力彎矩分正彎矩和負彎矩,抵抗負彎矩所配備的鋼筋稱為負筋,一般指板、梁的上部鋼筋，有些上部配置的構造鋼筋習慣上也稱為負筋。當梁、板的上部鋼筋通長時，大家也習慣地稱之為上部鋼筋，梁或板的面筋就是負筋）。

　　The definition of bending moment is that the lower part of the steel bar is tensioned positive, while the upper part of the beam and slab position is generally tensioned on the upper part of the support seat according to the force, that is, to bear negative bending moment, so it is called negative bending moment steel bar. (Bearing with negative reinforcement, is relatively speaking, should generally refer to the support part of the beam to offset negative bending moment of the reinforcement, commonly known as load-bearing reinforcement. The bending moment of general structural members can be divided into positive moment and negative moment. The steel bars equipped to resist negative moment are called negative bars. The upper bars of finger plates and beams are generally referred to as negative bars. When the upper reinforcing bars of beams and slabs are long, they are also customarily referred to as the upper reinforcing bars, and the gluten of beams or slabs is the negative reinforcing bars.

　　拉結筋在無法同時施工的兩個或多個構件之間預留的起拉結作用的鋼筋就是拉結筋 。是加強框架填充墻與柱連結的受力鋼筋，提高了填充墻穩(wěn)定性和抗震能力。

　　Tension bar is reserved between two or more members which can not be constructed at the same time. It is a reinforced bar that strengthens the connection between frame filled wall and column, and improves the stability and seismic capacity of filled wall.

　　腹筋一般位于梁兩側中間部位而得來的，是梁中部構造鋼筋,主要是因為有的梁太高，需要在箍筋中部加條連接筋 （梁側的縱向構造鋼筋實際中又稱為腰筋）。在梁高450mm，就應沿梁高兩側應設腰筋，所以數(shù)量上就不會少于2根。腰筋的直徑小的直徑為10mm，間距不應大于200mm，同時面積配筋率不應小于百分之0.3，在梁兩側的縱向構造鋼筋（腰筋）之間還要配置拉結鋼筋。 一般民用建筑的腰筋直徑用16和18就可以了，拉筋用圓8。

　　The web reinforcement is generally located in the middle part of both sides of the beam, which is the structural reinforcement in the middle of the beam. The main reason is that some beams are too high and need to add a connecting bar in the middle of the stirrup (the longitudinal structural reinforcement in the side of the beam is also called waist reinforcement in practice). In the 450mm beam height, waist reinforcement should be installed along both sides of the beam height, so the number will not be less than two. The minimum diameter of waist reinforcement should be 10 mm, the spacing should not be greater than 200 mm, and the reinforcement ratio of area should not be less than 0.3%. Tensile reinforcement bar should also be arranged between longitudinal structural reinforcement bar (waist reinforcement) on both sides of the beam. The diameter of waist tendons in general civil buildings should be 16 and 18, and the diameter of tension tendons should be 8.
