Nearly four out of five new homes built in America use manufactured roof trusses to frame the roof. Prefabricated trusses replace the rafters and ceiling joists used in conventional framing. The use of trusses enable the general contractor to construct homes that have more complex roof and ceiling...
These load bearing members can be created using many different types of mesh. In recent years, it has been observed that there are damages in the steel roof trusses due to heavy snowfall, especially in industrial buildings. Therefore, it is important to design these members safel...
Trusses are commonly used in various applications, including bridges, roofs, towers, and cranes. The basic components of a truss structure are the members and the joints. Members are typically made of steel or timber and can be either beam (horizontal members) or struts (diagonal or vertical ...
These bridges are built using cantilevers, which are structural elements extending horizontally and supported at only one end. In the case of small footbridges, cantilevers may be simple beams. However, for long cantilever bridges, box girders (built from prestressed concrete) or trusses (built fr...
The fire resistance ratings apply to structural building materials, including those used on exterior and interior bearing walls, columns, beams, girders, trusses, and arches, as well as floor, ceiling, and roof assemblies. There are 5 main types of buildings according to fire resistance rating: ...
Cables are used to support long spans where trusses are not feasible, resulting in a significant increase in cost and size of the structure. These can carry loads in tension and can be used for spans longer than 46m (150ft). These are employed in bridge structures, and the use of cables...
