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.

　　贯通筋是指贯穿于构件（如梁）整个长度的钢筋，中间既不弯起也不中断，当钢筋过长时可以搭接或焊接，但不改变直径

　　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.

　　架立筋和贯通筋有什么区别？

　　What is the difference between erecting tendons and perforating tendons?

　　在钢筋布置上，架立钢筋是布置本跨的1/3，也就是说，本跨梁存在左右支座钢筋。通长钢筋是全长布置。架立筋起架立作用，一定的受压作用，可以在一定程度上提高梁的承载力。

　　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.

　　贯通筋是指贯穿于构件（如梁）整个长度的钢筋，中间既不弯起也不中断，当钢筋过长时可以搭接或焊接，但不改变直径。贯通筋既可以是受力钢筋，也可以是架力钢筋。

　　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.

　　架力筋也有贯通的，如规范中规定在梁上部两侧的架力筋必须是贯通的，此时的架力筋在支座处也可承担一部份负弯矩。

　　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长的钢筋，一般在梁上（受压区）且直径较小的是架力筋，在梁下的是都受力钢筋。

　　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.

　　就是负弯矩钢筋，弯矩的定义是下部受拉为正，而梁板位置的上层钢筋在支座位置根据受力一般为上部受拉，也就是承受负弯矩，所以叫负弯矩钢筋。（支座有负筋,是相对而言的,一般应该是指梁的支座部位用以抵消负弯矩的钢筋，俗称担担筋。一般结构构件受力弯矩分正弯矩和负弯矩,抵抗负弯矩所配备的钢筋称为负筋,一般指板、梁的上部钢筋，有些上部配置的构造钢筋习惯上也称为负筋。当梁、板的上部钢筋通长时，大家也习惯地称之为上部钢筋，梁或板的面筋就是负筋）。

　　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.

　　拉结筋在无法同时施工的两个或多个构件之间预留的起拉结作用的钢筋就是拉结筋 。是加强框架填充墙与柱连结的受力钢筋，提高了填充墙稳定性和抗震能力。

　　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.

　　腹筋一般位于梁两侧中间部位而得来的，是梁中部构造钢筋,主要是因为有的梁太高，需要在箍筋中部加条连接筋 （梁侧的纵向构造钢筋实际中又称为腰筋）。在梁高450mm，就应沿梁高两侧应设腰筋，所以数量上就不会少于2根。腰筋的直径小的直径为10mm，间距不应大于200mm，同时面积配筋率不应小于百分之0.3，在梁两侧的纵向构造钢筋（腰筋）之间还要配置拉结钢筋。 一般民用建筑的腰筋直径用16和18就可以了，拉筋用圆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.
