Timber, being an environmentally friendly light-weight construction material and hence easy to handle, has been a popular material for the construction of light frame buildings. However, the inherent disadvantages associated with timber such as excessive creep, poor sound insulation, inferior stiffness and strength compared to other construction materials and limited fire-rating, among others, have limited its use as a structural material to low-rise buildings and relatively short spans. In this study, further conceptual advancement is made to a structural system called the 'timber-boxed concrete structural system'. This is envisioned to be a dual acting system utilizing the positive attributes of both dimensional timber and reinforced concrete. This system does not rely on composite action unlike the timber-concrete composite structural system, which heavily depends on the composite action between the constituent materials leading to higher construction and maintenance costs. A construction sequence is detailed for the proposed system which would ultimately result in a cost effective rapid construction practice. A metal stud stiffened timber-boxed reinforced concrete wall is also conceptualized. These walls will make the timber-boxed concrete structure stiffer, and this enables the construction of taller and larger structures. It is concluded that the conceptual system is ready for testing and implementation. Copyright © 2013 by Research Publishing Services.
