A cable brace, also known as wind bracing (used interchangeably), forms a taut connection in the shape of an “x” between frame structural members and attaches to the main frame or concrete. Metal buildings require cable bracing or x bracing to help transfer wind and seismic loads to the foundation. Cable bracing in metal buildings is critical!
Full Answer
What is a cable bracing system?
Cable bracing is a tension-only X-bracing system and is one of the most efficient ways to transfer longitudinal loads to the foundation in smaller low-rise buildings.

What is cable brace?
Cable bracing or other cross bracing in these walls provides a redundant force resisting system. If the screws tear through the metal sheets, the cables will take the load. Most likely, the wall panels and braces will work together to resist the loads.
What is structural cross bracing?
In construction, cross bracing is a system utilized to reinforce building structures in which diagonal supports intersect. Cross bracing can increase a building's capability to withstand seismic activity. Bracing is important in earthquake resistant buildings because it helps keep a structure standing.

Why is cross bracing strong?
Cross bracing between joists or rafters strengthens the members by preventing sideways deflection. This bracing is known by many names such as herringbone strutting, blocking, bridging, and dwanging.
Which types of bracing are commonly used in tall buildings?
There are two major bracing systems:Vertical bracing system.Horizontal bracing system.
How effective is cross bracing?
Full-height, steel cross bracing can increase a building's capacity to withstand seismic forces. Cross bracing can be exterior or interior and is secured to the building at floor level. Effectiveness: Somewhat to very effective, depending on pre-disaster building condition and the extent of cross bracing.
What are the four types of wind bracing?
Wind bracingIntroduction.Rigid joints between beams and columns.Shear wall.Lift shaft with solid walls.Theory of triangulation.
What are the different types of bracing used in braced building?
This consists of bracing at each floor in the horizontal planes thus providing load paths so that the horizontal forces can be transferred to the planes of vertical bracing. The horizontal bracing system is too divided into two major types namely: Diaphragms and. Discrete triangulated bracing.
Why is cross bracing important?
Cross bracing is used to keep buildings stable when the wind blows and during seismic events, such as an earthquake. It also limits the building's lateral movement, reducing the likelihood of damage to the structure's components and cladding.
What angle is best for bracing?
between 30° and 60°Bracing is most efficient when placed at angles between 30° and 60°. With steeper bevels, the end connections can be cumbersome.
Do you need diagonal bracing?
Diagonal bracing is really important if you're working with roof trusses on a room addition. Many a carpenter has been killed or seriously injured when roof trusses suddenly collapse as they're erected. Wind can easily push them over if they have no bracing.
How do you stabilize a structure?
first remedial task is to stabilize and consolidate the structure. Ideally, this is best done by restraining, or tying, the point of active thrust and then by replacing, splinting, or in some way giving fresh heart to any failing or defective member.
What is cable bracing?
Cable bracing (like rod bracing) is a tension-only X-bracing system. It is one of the most efficient ways to transfer longitudinal loads to the foundation in smaller low-rise buildings; however it has application limitations due to capacity constraints for buildings with mezzanines, cranes, or in high seismic areas.
What is a flange brace?
Flange. Flange braces are the structural members that attach purlins, girts, and eave struts to primary structural members (columns or rafters). They are used to prevent the main frame from twisting or buckling laterally under the load.
What is Robertson's bracing?
Robertson’s Bracing is a key element in creating a strong foundation to fight seismic, wind, and crane thrusts by transferring loads from endwalls and sidewalls to the foundation.
Where is rod bracing located?
Rod. Rod bracing (also called X-bracing) is a tension-only bracing system. It may be located in the roof and walls of a building between frame members , transferring longitudinal forces to the foundation.
What is a portal frame?
A portal frame is comprised of two columns and a rafter made of built-up material and is attached to the web of the sidewall columns.
What is ACS4 cable?
ACS4 is a serious cable, pre-stretched, cut under defined load, and manufactured to a specific design load for optimal performance. Where it pays to predict the exact behaviour of the cable, where it really counts, ACS4 must be selected.
What is stretch in rope?
Stretch or elongation is a characteristic of all cables and wire ropes, initially as permanent stretch when the load is first applied and the individual wires bed down, then as conventional elastic stretch within the wires as load increases.
What is a full locked cable?
The full locked cable is primarily used for higher load applications where resistance to deformation, surface compression (e.g. when using clamps) and good corrosion protection are essential. All cables are pre-stressed and manufactured to a nominated design load.
Where is Ronstan cable made?

What is metal bracing?
Metallic bracing systems are used between structural members of metal buildings and are a key element in transferring seismic, wind, and crane thrusts from end walls and sidewalls to the foundation.
What is a flange brace?
Flange braces are the structural members that attach eave struts, girts and purlins to primary structures. They are used to prevent the mainframe from twisting or buckling under the load.
What is a portal frame?
A portal frame is comprised of two columns and a rafter made of built-up material and is attached to the web of the sidewall columns. When bracing occurs in locations where accessories would interfere with rod-bracing, a portal frame can be used.
Why do metal buildings need cable bracing?
Metal buildings require cable bracing or x bracing to help transfer wind and seismic loads to the foundation. Cable bracing in metal buildings is critical! It is used in all seismic loads (except for D). Also, note that not all cable bracing can be removed.
What is portal bracing?
Portal bracing is made up of two columns that attach between the frame liner to the structural frame with a beam connecting them. In the instance that a metal building can’t have cable or wind bracing, the non-panel shear brace will need to have portal bracing. Or, it will need to have a wind column which is a single column ...
Is bracing the same as bridging?
Bracing and bridging are virtually the same thing, so the terminology used depends on the person you are talking to. To minimize confusion, we will use the term bracing for this blog posting. Bracing is used between structural members of metal buildings.
What is Bracing in construction?
Bracing is a construction method used to stabilize the building structure against lateral forces. It increases the capability of building structures to withstand lateral load due to wind and earthquakes.
What is the purpose of bracing?
The primary purpose of providing bracing is to provide stability to the structure and preclude the collapse of a structure due to earthquake or wind or effect of moving load such as a crane.
Types of Bracing System
The horizontal bracing system includes bracing at each floor in a horizontal plane offers load paths for the lateral forces to transfer them to vertical bracing planes.
