Abstract:	This research project aims to minimize the weight of a solid timber rectangular column under the influence of both flexure and compression while using design standards from Eurocode 5. A Microsoft Excel spreadsheet was developed to perform the optimization procedure with an objective function, which related the geometric dimensions of the beam (width, thickness and length), its material properties (timber density) and its resultant weight, which is a product of the four parameters (density, width, thickness and length). The derived objective function was then constrained to design constraints with regards the flexural and compressive loads acting on the timber column which were obtained from Eurocode 5. The eventual weight optimization was performed on a selected timber column under varying conditions of its axial load, lateral load, characteristic compressive strength and characteristic bending strength. It was observed that while increase to both the axial and lateral loads eventually increase the optimized mass of the column after some initial stagnation, increase in the characteristic compressive strength offers no variance to the optimized weight whereas the characteristic bending strength greatly reduces the optimal weight as it increases.
