1. Structural layout is adopted for the bottom plate of beam reinforcement plan. It is suggested that the other layers should be consistent with the plan except plate thickness marking, reinforcement, column number, secondary beam location and node number.

　　2. 梁配筋放大原則：超靜定次數越多，放大系數越小;超靜定次數越少，放大系數越大。這樣，懸挑梁和單跨梁、框支梁應適當放大，大跨度梁可適當放大。其它梁配筋可以少放大甚不放大。樓梯間的梯梁梯柱布置與平面輸入可能有不符，樓梯邊梁應考慮這些原因，適當放大。另，注意三跑四跑樓梯，荷載不要漏。

　　2. Beam reinforcement amplification principle: the more statically indeterminate times, the smaller the amplification coefficient; the less statically indeterminate times, the larger the amplification coefficient. In this way, cantilever beams, single-span beams and frame-supported beams should be enlarged appropriately, and large-span beams can be enlarged appropriately. The reinforcement of other beams can be enlarged less or not. Layout of staircase beams and ladder columns may be inconsistent with plane input, and staircase side beams should be enlarged appropriately considering these reasons. In addition, pay attention to three runs and four runs of stairs, load should not leak.

　　3. 梁配筋盡量配一排;配筋大可考慮配兩排;盡量避免在簡單的梁里出現三排鋼筋-----因外排鋼筋更有效。另可以定個這樣的原則，梁高470以內不允許出現三排鋼筋的配法。

　　3. Beam reinforcement should be arranged in one row as far as possible; two rows should be considered for large reinforcement; three rows of reinforcement should be avoided in simple beams as far as possible - - - because the outer rows of reinforcement are more effective. In addition, it can be established that three rows of steel bars are not allowed to appear within 470 girder height.

　　4. 拉通筋盡量可以用小的鋼筋-----應用在住宅等小跨度梁里。多直徑搭配直徑差距不宜超過兩級。如果在公建、商鋪等跨度較大、荷載較大的梁中，盡量用大鋼筋拉通，以減少根數，達到第3條的要求。

　　4. Pull-through bars can be used as small as possible in small span beams such as residential buildings. The diameter difference of multi-diameter collocation should not exceed two levels. If the girders with large span and large load, such as public buildings and shops, are pulled through with large steel bars as far as possible to reduce the number of roots and meet the requirements of Article 3.

　　5.第4條拉通筋用小的時候，局部可考慮2ф16+2ф20、2ф16+4ф20這樣的配法，以滿足配筋要求以及第3條要求;梁端支座如果寬度240，盡量用16及以下的支座筋，滿足錨固平直段0.4LaE的要求。

　　5. When the fourth pull-through bar is small, some methods such as 2 16+2 20, 2 16+4 20 can be considered to meet the reinforcement requirement and the third requirement. If the width of the beam end support is 240, the support bar of 16 or less should be used as far as possible to meet the requirement of 0.4LaE of the anchored straight section.

　　6. 局部薄弱部位和屋面可考慮3根面筋拉通，或者局部加強。

　　6. Three gluten pull-through or local reinforcement can be considered for local weak parts and roofs.

　　7. 梁底筋有條件的盡量用3根，比如原來配2ф16，可考慮配成3ф14。小梁可配成2ф14。框架梁建議梁底不少于3ф14。

　　7. Use three beams as far as possible when conditions permit. For example, the original 2 16 can be considered as 3 14. Trabeculae can be matched with 2 14. It is suggested that the bottom of the frame beam should not be less than 3 14.

　　8. 順梁方向支座(墻、柱)寬度為240時，梁縱筋單排盡量不超過3根。支座寬度大于梁寬不受此限制。

　　8. When the width of the bearing (wall, column) along the beam direction is 240, the longitudinal reinforcement of the beam should not exceed 3 in a row. The bearing width is larger than the beam width.

　　9.隔墻下小梁和簡支次梁，其架立筋和支座筋可用2Ф12。局部梁支座或與剪力墻搭牢的小梁計算負筋較大，實際配筋減小時，應注意本梁的調幅以及相關擱置梁抗扭、抗彎的受力變化。

　　9. Under the partition wall, the trabecular and simply supported secondary beams can be erected and supported with 2 12. When the actual reinforcement is reduced, attention should be paid to the amplitude adjustment of the beam and the changes of the torsional and flexural forces of the related shelved beams.

　　10. 注意雙節點柱的計算，以及兩個方向梁計算與配筋的變化，可考慮實際受彎情況和約束可能人為調整。

　　10. Attention should be paid to the calculation of double-node columns, the calculation of two directional beams and the change of reinforcement. The actual bending situation and restraint may be adjusted artificially.

　　11. 要注意：標準層的梁高，到上一層和下一層(特別是下面與商鋪交接的部位)是否有必要和標準層一樣，這樣可以減少一些不必要的變截面和過小截面。

　　11. Attention should be paid to whether it is necessary for the girder height of the standard layer to reach the top and bottom layers (especially the junction between the lower and the shops) to be the same as that of the standard layer, so as to reduce unnecessary variable cross-section and too small cross-section.

　　12.梁布置原則：合理的梁布置可以使結構的超靜定次數增多，梁平面布置是控制次梁級數。少出現3級次梁，避免4級次梁。樓電梯間前室、過道、門廳梁布置要考慮今后裝修。盡量避免直接對門和打破一個開敞空間的梁布置。

　　12. Beam layout principle: Reasonable beam layout can increase the number of statically indeterminate structures, and beam layout is to control secondary beam series. Less 3-grade secondary beams, avoid 4-grade secondary beams. The layout of the front room, corridor and hall beam of the elevator room in the building should be considered for future decoration. Avoid direct door-to-door and beam layout that breaks an open space as far as possible.

　　13. 配筋時應注意同一跨梁內上下鋼筋是否匹配、相同或類似部位梁鋼筋是否一致(同層和不同層)、主梁和次梁鋼筋是否協調。

　　13. When reinforcing, attention should be paid to the matching of the upper and lower reinforcing bars in the same span beam, the consistency of reinforcing bars in the same or similar parts of the beam (the same and different layers), and the coordination of reinforcing bars in the main beam and the secondary beam.

　　14. 梁寬350及以上采用4肢箍，上下鋼筋應大于等于4。跨中部位面筋可用2根拉通筋+2ф12。

　　14. Beam width 350 and above should be 4 limbs hoop, upper and lower reinforcement should be greater than or equal to 4. The gluten in the mid-span position can be made up of two pull-through bars + 2 12.

　　15. 附加箍筋和吊筋不可漏，注意：a.作為算跨數的依據;b.改梁箍筋是有可能會改變吊筋大小或有無;C.商鋪、大跨次梁、共建、梁上立柱往往有吊筋。

　　15. Additional stirrups and suspension bars should not be omitted. Attention: a. As the basis for calculating span; B. Beam stirrups may change the size or absence of suspension bars; C. Shops, long-span beams, co-constructions and columns on beams often have suspension bars.

　　16. 注意框梁KL和連梁LL的區別(數據顯黃為LL)，箍筋構造不同。

　　16. Note the difference between frame beam KL and connecting beam LL (data show yellow as LL), stirrup construction is different.

　　17.圓弧梁以及側邊無樓板梁的計算與結果判斷。注意扭矩折減系數，參數經常是用0.4。辦法：為這些梁a.修改折減系數和梁剛度放大系數;b.圓弧梁輸入多節點。

　　17. Calculation and result judgment of arc beam and side Slab-Free beam. Pay attention to the torque reduction factor. The parameters are usually 0.4. Solutions: For these beams a. Modify reduction coefficient and beam stiffness amplification coefficient; B. Arc beam input multi-node.
