Fire Blocking
Fire blocking or firestopping is a system of supplemental components in a wood-framed wall or ceiling, which prevents the rapid propagation of fire within a combustible framing cavity to other areas. Description and function In wood framed construction, fire blocking usually takes the form of short lengths of the same dimensional lumber used in the wall or floor/ceiling framing, installed perpendicular to the primary structural framing, completely obstructing the wall cavity. The International Residential Code (IRC) and International Building Code (IBC) both require fire blocking in combustible construction at transitions between horizontal and vertical framing, and in vertical cavities at intervals at no more than spacing between blocking, at the top and bottom of stair framing, and within exterior cornices. Other materials used for fireblocking may include noncombustible materials such as gypsum board, cement board, or mineral fiber insulation blankets Fire blocking is most cr ...

International Residential Code
The International Code Council (ICC), also known as the Code Council, is an American nonprofit standards organization sponsored by the building trades, which was founded in 1994 through the merger of three regional model code organizations in the American construction industry. Since 2023, ICC's headquarters has been based at Capitol Crossing in Washington, D.C. The organization creates the International Building Code (IBC) and International Residential Code (IRC), two model building codes, which have been adopted for use as a base code standard by most jurisdictions in the United States. The ICC's model codes have been criticized for inflating housing costs and reducing housing supply in the United States through arbitrary and stringent standards that do little for safety and are out of sync with best practices in other countries. The IBC has contributed to the spread of 5-over-1 type of buildings across the US and contributed to a lack of medium-density housing (so-called "m ...

Framing (construction)
Framing, in construction, is the fitting together of pieces to give a structure, particularly a building, support and shape. Framing materials are usually wood, engineered wood, or structural steel. The alternative to framed construction is generally called ''mass wall'' construction, where horizontal layers of stacked materials such as log building, masonry, rammed earth, adobe, etc. are used without framing. Building framing is divided into two broad categories, heavy-frame construction (heavy framing) if the vertical supports are few and heavy such as in timber framing, pole building framing, or steel framing; or light-frame construction (light-framing) if the supports are more numerous and smaller, such as balloon, platform, light-steel framing and pre-built framing. Light-frame construction using standardized dimensional lumber has become the dominant construction method in North America and Australia due to the economy of the method; use of minimal structural m ...

Cross Bracing
In construction, cross bracing is a system utilized to reinforce building structures in which diagonal supports intersect. Cross bracing is usually seen with two diagonal supports placed in an X-shaped manner. Under lateral force (such as wind or seismic activity) one brace will be under tension while the other is being compressed. In steel construction, steel cables may be used due to their great resistance to tension (although they cannot take any load in compression). The common uses for cross bracing include bridge (side) supports, along with structural foundations. This method of construction maximizes the weight of the load a structure is able to support. It is a usual application when constructing earthquake-safe buildings. Cross bracing can be applied to any rectangular frame structure, such as chairs and bookshelves. Its rigidity for two-dimensional grid structures can be analyzed mathematically as an instance of the grid bracing problem. Cross bracing may employ ...

Uniform Building Code
The Uniform Building Code (UBC) was a building code used primarily in the western United States. History The UBC was first published in 1927 by the International Conference of Building Officials, which was based in Whittier, California. It was intended to promote public safety and provided standardized requirements for safe construction which would not vary from city to city as had previously been the case. Updated editions of the code were published approximately every three years until 1997, which was the final version of the code. The UBC was replaced in 2000 by the new International Building Code (IBC) published by the International Code Council The International Code Council (ICC), also known as the Code Council, is an American nonprofit standards organization sponsored by the building trades, which was founded in 1994 through the merger of three regional model code organizations in th ...

Firestop
A firestop or fire-stopping is a form of passive fire protection that is used to seal around openings and between joints in a fire-resistance-rated wall or floor assembly. Firestops are designed to maintain the fire-resistance rating of a wall or floor assembly intended to impede the spread of fire and smoke. Description Firestops prevent unprotected horizontal and vertical penetrations in a fire-resistance-rated wall or floor assembly from creating a route by which fire and smoke can spread that would otherwise have been fire resisting construction, e.g. where a pipe passes through a firewall. Fire stopping is also to seal around gaps between fire resisting constructions, e.g. the linear gap between a wall and the floor above, in order for construction to form a complete barrier to fire and smoke spread. Opening types Firestops are used in: * Electrical, mechanical, and structural penetrations * Unpenetrated openings (such as openings for future use) * Re-entries of exi ...
