Laminated Bamboo Lumber, or LBL, has been used in many architectural products; however, it is still new as a structural material in building construction. Bamboo, as a renewable material, is used to produce LBL, so that it can gain sustainable benefit. Many experiments using LBL as a building and construction material have been demonstrated globally however, there is no strong evidence of the commercial use of LBL as structural material. This research investigates the viability of LBL in three major parameters; structural, architectural, and sustainable parameter. The methodology used consisted of a thorough literature review and the physical testing of LBL beams analyzed with parallel calculations. In physical tests, other wood engineered products, other than LBL beam specimens, were used as controls for comparison. They are Laminated Veneer Lumber (LVL), Glue-laminated Timber (Glulam), Parallel Strand Lumber (PSL), and Oriented Strand Lumber (OSL). The tests found maximum load and maximum stress to collapse the beams, and maximum deflection before collapsing, and finally the Young's modulus of elasticity of the material. The allowable load and allowable stress were tabulated by using found maximum data. The results were plotted into simple charts for architects and builders to use in designing and selecting the proper sizes and spans. In architectural parameter, the research investigates what it takes for LBL to be used in an architectural project. Investigations focus on project workability, fastening, project cost analysis, and building code. Research also provides design explorations for taking advantage of the unique tapered character of bamboo and simple design guidelines for how architects and designers can easily adopt this material in their projects. The research also explores LBL's sustainability value as being a green material and how a project can be sustainable using LBL. The final aim is to endorse the use of LBL as a viable structural material, and furthermore, to aid in the adoption of LBL as a widely used structural material in architectural design.
