North Light Roof Truss Wikipedia

Roofs of long span structures are made of steel trusses.

North light roof truss wikipedia.

This type of truss is seen in a framed roof consisting of rafters and a ceiling joist and in other mechanical structures such as bicycles and aircraft. North light truss has a asymmetrical profile with a south facing slope at 17 or more to horizontal and the north facing slope at from 60 to vertical. North light is natural light coming from the north in the northern hemisphere. The steeper surfaces are glazed and face away from the equator to shield workers and machinery from direct sunlight this kind of roof admits natural light into a deep plan building or factory.

A saw tooth roof is a roof comprising a series of ridges with dual pitches either side. It consists of light which comes from the blue sky rather than directly from the sun. This sort of roof commonly admits natural light into a factory and is also known as northlight in the northern hemisphere implying a single such plane. It is also preferred natural light by artists as well.

North light truss this form of truss is usually used for short spans in industrial buildings and is so called because it allows maximum benefit to be gained from natural lighting by the use of glazing on the steeper north facing pitch sometimes referred to as a sawtooth roof. Because of the stability of this shape and the methods of analysis used to calculate the forces within it a truss composed entirely of triangles is known as a simple truss. A roof appended thus the name to the wall of a building and by implication having further roofs or terraces above. Because of the steel pitch of the north facing slope the space inside the roof trusses of a north light roof is considerably greater than that of a.

The simplest form of a truss is one single triangle. It is diffused sun light and hence does not create sharp shadow.
