Construction industries make use of Bamboo because of its high strength, growth rate and abundance in most parts of the world. Bamboo is one of the oldest building materials used by man, (Abd.Latif et al., 1990). Unfortunately, local bamboo species in Ghana have not been used in such engineering applications even though bamboo is abundant in the country. The objective of this work is to study the mechanical properties of Ghanaian Bamboo and establish its suitability for structural engineering applications. Two types of bamboo, the bambusae vitata and the bambusae vulgaris, were used to perform tensile tests to determine the yield strength, ultimate strength and the modulus of elasticity; while bending tests were conducted to determine the modulus of elasticity and ultimate strength. The studies found a linear relationship between the applied loads and the corresponding extensions for tensile and bending tests. The yield and ultimate strength properties of the species improved as the number of days increased due to possible reduction in moisture content. Similar results were obtained for the bending tests. The results also showed that the properties obtained were well within the range of foreign bamboo species. It was concluded that the mechanical properties of the local bamboo have been characterized by determining their yield strength, ultimate strength and modulus of elasticity. It can therefore be established that, the two species under study can be used in engineering application.
