Abstract

This research focuses on developing connections for an innovative pavilion demonstrator using bent wood. The techniques of bending and compressing wood are employed here. The starting point for the demonstrator design was a spherical polyhedron with 132 pentagonal faces (132-Pentagon Polyhedron), which offers a highly symmetrical geometry from only three different shapes. The core of this work is to demonstrate the load-bearing capacity of the entire structure and especially the connections. For this purpose, models were created using the finite element method program. These models were used to determine the internal forces and stress distributions, which were then utilized for the design. Based on these results, the connections used in the structure were designed. Two types of mechanical connections are being tested: one purely wood-based (utilizing compressed wood) and the other incorporating steel bolts. The experimental phase involves bending, shear and push-out tests on the samples to evaluate their performance. This study aims to enhance the sustainability and structural efficiency of timber constructions by reducing reliance on adhesives. Key findings and methodologies are detailed in this paper, providing insights into the mechanical properties and feasibility of these connections.
