Library

The ABIS library is a collection of useful reference material relating to buildings and their problems as well as timber pests such as termites.

The library is a combination of material written by ABIS as a result of our own research and practical experience together with useful information gleaned from other authoritative sources.

 

Ridge Beam

The Ridge Beam is the horizontal timber beam at the apex of the roof. It has no structural function but is the member against which the high ends of the rafters lean. It ensures that the rafters meet in a straight line and stay upright.

Where a trussed roof is used, the rafters are the top chord of the truss and truss action spans the width of the building. In other cases, the rafters must span from the top of the roof to the top of the walls. The ridge beam supports the rafters at the top of the roof and is a bending member spanning between its supports (generally across rooms).
