Wood frames are not only very economical to build but are also resistant to extreme climatic variations, and offer residents a high degree of comfort. Added to that, wood frames are sustainable and absorb carbon and offset greenhouse gasses. Wood frames can be used to construct different styles of buildings and there cannot be any restriction on architectural possibilities when wood is the medium.
In order for a wood building to perform its expected functions, it is necessary to construct it judiciously and this can be achieved by using sound construction and erection practices.
For instance, wood frames are light in weight and hence it does not require cranes and other heavy machinery for the erection process therefore contributing to the economic aspect of construction. Based on the type of soil and wood frame loads, a suitable foundation is specified for construction. Footings should be deep enough to avoid frost action in winter. The ground needs to be sufficiently compacted if the structure is constructed in an area where root trees have been removed or filled materials are placed.
If the wood frame is constructed over poor soil, treated wood pile with wood or concrete sills can be used. By and large, two types of foundations are widely used for wood structures: namely concrete foundation and pressure preservative treated wood foundation which are shown in Fig. Apart from these, free standing pier, piers with curtain walls, and pier supporting grading beam can also be utilized.
After the foundation has been laid, construction of wood frame structure begins. There are various types of techniques that can be used for the construction of wood frames. Suitable construction technique should be selected for a given wood structure:. It is an easy method and mostly suitable for the construction of houses.
In this technique, first-floor joists are covered with sub-flooring to create a surface upon which exterior walls and interior partitions are erected. In the platform system, wall framing can be assembled on the floor and the entire unit can be tilted into its place. It is another method of wood frame construction which although is a bit less popular compared to platform frame construction, but is utilized when the conditions ask for it.
In this method, exterior wall studs and first-floor joists are supported by anchored sill. The exterior wall studs are continuous to the second floor. The second-floor joists are supported by ribbon strip which are inserted into the inside edges of exterior wall studs.
