What is bracing?
Bracing refers to serving support to steel structure. Bracing is a construction technique that uses rods, cables, or angles to improve the stability and safety of a pre-engineered building.
What is the purpose of bracing?
Bracing systems help maintain a building’s structural integrity by transferring loads like wind or seismic forces to the foundation. They also help to evenly distribute loads and resist lateral forces.
Provision of bracing and dampers results in lateral stability. Once distribution dampers or bracings are added, the overall system changes to a lateral load-resisting system (LLRS). If the buildings are not designed to resist the lateral masses, then perhaps collapse leading to the loss of life or its content is why bracing in PEB plays a very important role. The number of braced bays depends on building size, height, wind loads, seismic loads, etc.
Types of Bracing:
Cross Bracing:
It is the most common type of bracing. Depending on design loads, an “X” between two rigid frames. Rod bracings or pipe bracings, are being used.
Portal Framed Bracings:
It is an expensive solution but required if cross bracings are an obstacle for men and machine movements. Portal bracing is a secondary rigid frame between two primary rigid frames in a bay. They are similar in construction to a rigid frame with two columns and a rafter.
Flange Braces / Purlin Stays:
Flange braces are required to counteract compression, shear, torsion and lift forces. They are structural angles connected between the rafters & purlins, columns & girts. Purlin Stay is standard for all steel buildings and prevents rafters from moving under a load.
Portal Bracing:
Commonly used at the end walls of PEBs, portal bracing consists of vertical columns and horizontal beams that create rigid frames to resist wind loads.
Sag rods bracing
For preventing the sagging of an open-web steel joist that is used as a purlin with its depth at right angles to a roof slope.
Benefits of bracing in steel structures/PEB
Bracing systems greatly increase a building’s strength and stability, allowing it to endure lateral forces like wind and earthquakes. They disperse these stresses across the entire building, reducing structural damage.
When a building is subjected to windstorms or seismic activity, bracing systems serve to limit the amount of damage that it sustains. Bracing decreases the danger of structural failure and the expense of repairs by efficiently distributing the stress.
Bracing systems improve the structural integrity of a building, extending the life of the structure. Bracing lessens the possibility of early deterioration by protecting the structure from wear and tear.
In summary, bracing systems are crucial to construction because they offer strength, stability and resistance to lateral stresses. Bracing systems provide advantages like more strength, less damage and a longer lifespan, but they can also have disadvantages like higher costs, less flexibility and maintenance requirements. Selecting the ideal bracing system for a building project requires careful thought and expert advice.
