Moment Frame Pitched Roof

The anatomy of a steel portal frame can be broken down into four key in plane components.

Moment frame pitched roof. However in practise they tend to be much shallower commonly being expressed as a gradient and can be anywhere from 1 40 to 1 80. Pitched roofs are generally used where rainfall is heavy. The roof pitch is typically set to 5 10º with portalised bays at 6 8m centres longitudinally. D connections between rafter and column eave joints and splice in the rafter at apex apex joint.

If buildings are constructed with some limited width then also we can go for pitched roofs. To frame this style roof hip trusses are utilized from the main peak of the building stepping down with a flat top chord. When using a truss 1 roof the framing process. Robin is working on an extension so we thought we d shadow him for the day and see how he creates a pitched roof or semi pitched roof leading up to a flat.

A hip set is then used to frame the 6 or 8 feet nearest the end wall. A pitched roof is in contrast to a flat roof which technically is any roof with a slope less than 10. It uses a single mono truss 1 and often has a pitch lower than 3 inches per foot 2 making it easy to roof but hard to maintain. We know that the roofs are generally provided at top to cover and protect the structure from different weather conditions.

Mono the mono roof is a single very low pitched roof used mostly on contemporary homes. The flat portion is increased the nearer the truss is to the end wall.
