Tensile strength class system for Malaysian hardwoods according to European standards EN 384 and EN 408 / Nurul Izzatul Lydia Za‘Ba

Timber has been widely used as load-bearing building elements such as roof trusses, beams and columns subjected to tensile, shear, bending and compression loading. In order to design such structural system, the strength properties of a timber need to precisely determined. Currently, in Malaysia, the...
