Steel Bracing In Braced Multi Storey Frames

Steel Bracing in Braced Multi-storey Frames

Steel bracings within a braced multi storey steel arrangement can be classified into two types; horizontal bracing and vertical bracing.

Horizontal Bracing:

When lateral forces are applied on a braced frame, the forces are first received by the building cladding, and then to the horizontal bracing which consequently transfers it to the vertical bracing from where it reaches the foundation. The primary function of a horizontal bracing is to provide a route or load path through which all applied lateral forces would reach the foundation. Thus, horizontal bracings are provided on the horizontal plane of each floor level.There are two forms of horizontal bracing that can be provided within a multi-storey steel braced frame. These are:

• Diaphragm
• Triangulated Bracings

A diaphragm is the part of a structure that provides bracing in its plane. Usually, these are floor slabs or roof cladding, but they can also be in vertical cladding elements. In steel braced frames, diaphragms are tied back to vertical bracings of the structure that provide lateral stability. In-situ concrete slabs, metal decks, and timber floors are all excellent forms of diaphragm, albeit they may sometimes require some assessment for strength sufficiency in resisting the applied lateral loads.In the absence of a sufficiently stiff diaphragm, Horizontal bracing may be used, in the form of steel bracing. The bracings are arranged in the form of a modified warren truss or the modified fink truss format as shown in Figure 2. The modified fink truss is more suited for tension bracing. In both cases the floor or beams act as part of the horizontal stability system and therefore must be designed for tension or compression in addition to flexure and shear.

Vertical bracings comprise of the diagonal bracing elements in the vertical plane of the structure provided in both orthogonal direction of the steel frame. This part of the bracing system is responsible for transferring the applied lateral forces down to the foundation. They are usually provided by bracing two lines of columns from the ground-up, just like a vertical cantilevering truss. In order for a vertical bracing to be effective, it must be provided at each floor level, throughout the entire height of the steel frame.

Shoring or Bracing is the construction of a temporary structure to support temporarily an unsafe structure. These support walls laterally. Shoring

can be used when walls bulge out, when walls crack due to unequal settlement of foundation and repairs are to be carried out to the cracked wall,

when an adjacent structure needs pulling down, when openings are to be newly made or enlarged in a wall.
