Summary of steel structure residential design

This paper analyzes the characteristics of steel structure residential system from the design point of view, and introduces the design idea of special-shaped steel column residential project. The data of frame structure with different damping ratio and foundation scheme are compared and analyzed; Summarize the common problems and precautions in the design; Put forward different opinions on design standards.

Selection of steel structure residential system

From the perspective of the completed steel structure residence, it mainly includes:

1) Form of thin-walled section steel composite wallboard;

2) Pure frame form;

3) Frame support form;

4) Steel reinforced concrete composite form;

5) Steel frame concrete seismic wall form, etc.

These structural forms have their own characteristics. Among them, the thin-walled section steel composite wallboard form is particularly suitable for finalized products. Its system evolved from the wallboard structure, that is, the thin-walled section steel column members are arranged at a spacing of about 600mm to form a vertical load-bearing structure, the section steel is provided with a support system to resist horizontal force, and the floor slab is arranged into a multi ribbed support structure according to the position of the vertical section steel, Because the superstructure is an inner wall panel structure, its foundation is set as a strip foundation according to the stress conditions, and the requirements for the foundation are not high. The thin-walled steel composite wallboard residence is affected by the dense structure, which has certain restrictions on the size of bays, door and window openings and protruding components.
