Timber design: reimagining steel pavilion with wood

Abstract

This project explores the structural redesign of an existing steel pavilion using engineered timber. The objective is to understand and apply the principles of timber construction by replacing steel elements with timber alternatives like glulam and CLT components while maintaining the original architectural design. Using Eurocode 5 as the primary design framework, the study involves a complete structural analysis under gravity and wind loads, leading to the sizing of members and design of complex joinery. Analytical tools, including ‘Staad Pro’, ‘Robot Structural Analysis’ and custom Excel-based design sheets, were employed to evaluate structural performance under compression, tension, bending, and shear forces. Additionally, critical joineries were designed for strength and stability, accounting for tension, shear, and moment transfer. Through comparative analysis, the project highlights both the opportunities and challenges in timber design, including fire resistance, durability, and connection detailing.
