Roof Trusses Huws Gray Timber Engineering August 2020 this document is intended to be used by engineers to provide guidance in designing and evaluating timber roof truss structures. do not attempt to design a timber roof truss structure without adult supervision from a qualified professional (preferably an experienced timber engineer). the timber frame engineering council (tfec) and the timber framers guild (tfg) assume no liability. Truss and purlins structural design analysis free download as pdf file (.pdf), text file (.txt) or read online for free. this document summarizes the design of purlins for a roof with a pitch of 1.2 meters and span of 11.5 meters. Roof trusses builders want solutions that help them stay on schedule and maintain quality construction and profits. when compared to traditional beam construction, manufactured wood roof truss systems are better, stronger, and can be installed faster. a manufactured truss is an engineered structural component assembled from wood members, metal connector plates and other mechanical fasteners. The historical performance of wood construction, whether exposed to hurricane force winds, earthquakes, or fire can be attributed to two factors, òstructural redun dancy within the trussó and òload redistribution across the floor or roof.ó there is structural redundancy within each truss.

Roof trusses are characterised by an economic use of construction materials (timber, steel). composed of individual lightweight pieces, a truss can also provide considerable advantage in transport and assembly as compared to conventional roof structures. These trusses are usually used floor systems, but can be provided as roof trusses because you can achieve shallow depth trusses when you utilize system 42s. these trusses can sometimes be manufactured using 3x2 lumber instead of 4x2 lumber.
