A Novel Hybrid Wooden Structural System for Multi-Storey Buildings in Seismic Prone Areas

The development of innovative engineered wood products has greatly increased the possibility of using timber as structural material, opening new markets in the construction sectors, such as multi-storey residential and collective (e.g., schools) buildings. The use of timber structures is in fact still confined to low- and mid-rise buildings. The HyWood4Buildings project aims to overcome the existing constraints in the timber construction sector, proposing a novel hybrid structural system for taller timber buildings. This system combines two distinct but interacting components: a modular hybrid steel-timber lateral load resisting (HyST-LaR) system and a solid-sawn wall (SoN-Wall) system. This paper presents the structural characterization of the innovative HyST-LaR system through an experimental campaign at component-level and numerical analysis with a first glance to the development of an analytical model.
