The use of tropical hardwoods in structural applications requires knowledge of the mechanical properties. Even though long experience is available with the species azobé (Lophira alata), much of the current knowledge is based on tests performed on small clear specimens for bending, compression and shear. Since tropical hardwoods are used in structures with high economic value, a sound knowledge of the mechanical properties allows for better optimisation and for minimal use of raw material. Bending, compression and shear tests have been performed on material in structural sizes. Characteristic values show that in most loading cases the structural capacity of the material is distinctly higher than currently assumed in practice. The relationship between static modulus of elasticity and bending strength has been determined. The depth effect was shown to be less pronounced than for softwoods
