The general instruction of architectural design is very important for structural design, because the general instruction of architectural design will mention many practices and many data to be used in structural design, such as the location of the building (used to determine the fortification degree in the structure and the wind load and snow load) and the elevation of the Yellow Sea (used to calculate the foundation size and the elevation of the top of buried piles). Without the altitude of the Yellow Sea, it is impossible to carry out construction).

Wall practice, floor practice, floor practice, etc. (used to determine the load of each part), in short, the architectural design instructions should not be read hastily, which is a very important link for the correctness of structural design.

For local sections that cannot be clearly expressed in plan and elevation, structural engineers can get more accurate height information and local height change of the section, which directly determines the sinking or lifting of the beam at the section relative to the floor elevation, or staggered beams, sandwich beams, short columns, etc.

Stair is an indispensable part of every multi-storey and high-rise building, and it is also a very important part. Stair details are divided into plan and stair profile, and architects need to carefully analyze the composition of each part of the stairs, whether it can form a whole.

When calculating stairs, the stair detail drawing is the only basis, and all calculated data are the obtained stair detail drawing, so the thickness of ladder beam, the thickness of ladder slab and the structural form of stairs must also be considered clearly when looking at the stair detail drawing.
