The shear wall structure arranged around the inner core to form a closed core structure system or the vertical bracing are placed along the periphery of the core area. And steel frame surrounding the outside of the structure. The frame-core is widely adopted in high-rise buildings and has also been applied in multi-story steel structure buildings in recent years.
The core structure has excellent lateral rigidity and strong torsion resistance. Generally, it is used as an elevator, stairwell, or bathroom. It not only improves the utilization rate of materials but also achieves practical effects in construction. The collaborative work of the hull core and the frame can quickly meet the limits of the inter-layer displacement and the overall deformation of the structure.

Advantages of Steel Structure Multi-story Building:
Good seismic performance:
Due to the excellent ductility of steel, it can not only weaken the earthquake response but also make the steel structure have the ability to resist substantial earthquake deformation.
Lightweight:
It can significantly reduce the vertical load and seismic action transmitted from the frame structure to the foundation.
Make full use of building space:
Due to the small column section, the building area can be increased by 2~4%.
The construction speed is fast:
A large space is formed, the plane layout is flexible, the rigidity of each part of the structure is relatively uniform, the system is simple, and the construction is easy.
