According to the high code, the height of the frame beam is118 ~112, the live load of the workshop is large, and the main beam section is 350*650 or 350*700. The secondary beam must be more than 50mm smaller than the main beam section, which is 300*600 or 300*550. It is enough to choose secondary steel for the main reinforcement, with the diameter between 18 20 22 25, 16 for the secondary beam, and 28 for the main reinforcement, so it should be used as little as possible. The diameter of 32 is rare in construction, so don't choose it. The stirrup diameter is between 8 10, and 65438+ is considered for some large stirrups. But try not to use secondary steel, because it is not convenient to hook! The main girder is divided into encrypted area and non-encrypted area. Generally, the stirrup spacing in the encrypted area is 100, and that in the unencrypted area is 200. For example, the circle 8@ 100/200 represents the stirrup of the beam. You can refer to the Pingfa Atlas 03G 10 1- 1.

The thickness of one-way slab is not less than 1/40 of the span, and the thickness of two-way slab is not less than 1/50 of the span. If the load is heavy, it will be considered separately. You can use 160 or 180 for trial calculation. I think it should be about the same. If the reinforcement ratio is large, 200 is definitely enough. When reinforcing steel bars, the plates will be reinforced and reinforced.
