Abstract
Glued-Laminated Timber (GLULAM) is a wood-based product often used in construction in many countries such as the USA, Canada, and many countries on the European continent. Briefly, GLULAM can be defined as wood layers glued together for a structural application. This way, GLULAM becomes viable for floors, beams, stairs. In addition to low density, GLULAM is a sustainable option for civil construction due to transportation's direct reduction of carbon dioxide emission in the atmosphere. In this sense, applying a consolidated technique to find regions where structural substitutions can be made, becomes attractive for direct manufacturing cost reduction or new blended GLULAM structures such as GLULAM combined with steel to improve the its performance. One of the best-known ways to change the performance of structures is through Topology Optimization. Therefore, in this work, is proposed an adaptation of the Bi-direction evolutionary structural optimization (BESO) to position steel bars in GLULAM structures submitted to static loads. By creating the concept of sub-design domain and applying the optimization theory. For this, ANSYS software is used to solve the finite element problem in conjunction with Matlab software, where the developed methodology is implemented to solve the topological optimization problem. As a result of applying the proposed method, the GLULAM structure can have additional properties to those already existing.
