Sloping Flat Roof Steel Truss Design

Per ft for proper drainage although steeper slopes are often desirable.

Sloping flat roof steel truss design.

The steel roof truss is one of structural engineering s most important and iconic elements. Roofs should have a minimum slope of in. For many single storey buildings sloping roofs on trusses are common. Made of individual members with equal counteracting tensile and compressive forces its purpose is designed to behave as a single object which carries supports a load over a span.

If you want to build a flat roof then you will need to build a flat roof truss. Also need sloping roofs and hence roof trusses. These are designed to span the space between two load bearing walls and take the weight from the roof onto these walls. A flat roof truss is also known simply as a flat truss and is not completely flat but rather slightly sloped in order to allow water to run off of the roof.

For flat trusses a minimum depth to span ratio between 1 8 and 1 10 is recommended the deeper trusses being preferred for the longer spans. These structures generally have a flat roof structure because they are already at a high height. Sloping flat trusses are typically supported by a ridge beam or girder truss at the roof peak and have sloping flat trusses on both sides to create wide open span spaces in public venues like riding arenas and churches. Workshops warehouses industrial buildings etc.

At places of heavy rainfall or heavy snowfall sloping roofs are necessary which have to be supported by roof trusses. They are used in construction of roofs of fairly large objects such as shopping malls logistical parks and warehouses.
