What is bracing in construction?

A bracing system is a secondary but essential part of a bridge structure. A bracing system serves to stabilize the main girders during construction, to contribute to the distribution of load effects and to provide restraint to compression flanges or chords where they would otherwise be free to buckle laterally.

What is the purpose of bracing?

The primary function of bracing is to provide stability and resist lateral loads, either from diagonal steel members or from a concrete ‘core’. For bracing frames, beams and columns are designed only to support vertical load, since the bracing system should carry all lateral loads.

Do I need wall bracing?

Why is Wall Bracing Needed? Wall bracing provides racking resistance against horizontal (lateral) racking loads from wind and earthquakes and prevents the wall studs from distorting in the plane of the wall (racking) in “domino fashion” and, thus, prevents building collapse.

Where does a brace go in a building?

The bracing at each floor (in horizontal planes) provides load paths for the transference of horizontal forces to the planes of vertical bracing. Horizontal bracing is needed at each floor level, however, the floor system itself may provide sufficient resistance. Roofs may require bracing.

What is a diagonal brace in construction?

Diagonal bracing is a structural component of just about any building. It provides lateral stability, preventing the collapse of walls, decks, roofs and many other structural elements.

What is the importance of bracing system in construction?

The bracing systems are necessary for structures that are subjected to lateral loads due to earthquake, wind, etc. They help in minimizing the lateral deflection of the structure. We can say that the beams and columns of the framed structure carry vertical loads while the bracing system carries the lateral loads.

What is the Council for masonry wall bracing’s standard practice?

It is based on principles set forth in the Council for Masonry Wall Bracing’s Standard Practice for Bracing Masonry Walls Under Construction (ref. 1), but has been updated in accordance with the design provisions of the 2011 Building Code Requirements for Masonry Structures (MSJC, ref. 2).

Should plan bracing be cast within the structure on completion?

If plan bracing is not cast within the deck and is going to remain in the structure on completion, the performance of the bracing in service needs to be verified. Because the bracing is spanning partly in the longitudinal direction, longitudinal stresses will be induced in the bracing.

What is the stiffness of the plan bracing system?

This requires determination of the stiffness of the plan bracing system. The stiffness of the plan bracing system is the stiffness of the whole structure.
