Development and Experimental Validation of a Timber Beam-to-Steel Column Connection with Replaceable U-Shaped Fuses
https://orcid.org/0009-0002-4557-1176
This paper proposes an innovative hybrid timber beam-to-steel column connection for seismic design of multistory buildings. This innovative connection consists of a set of two U-shaped steel fuses connecting a glulam beam to a steel column. U-shaped fuses are designed to dissipate seismic-induced energy and can be replaced after a moderate or potentially strong seismic event. Eight full-scale experiments were conducted, involving four glulam beam specimens with varying thicknesses and eight pairs of fuses with two U-shaped plate configurations (open-fuse and closed-fuse). The key connection performance metrics, including the flexural stiffness and strength, hysteresis response, ductility, and energy dissipation capacity, were investigated using the test results. A set of mechanics-based equations is proposed to estimate flexural stiffness and strength of the connection. The results of the experimental program confirmed that the proposed hybrid connection exhibits a stable hysteresis response without noticeable strength degradation and possesses excellent ductility and energy dissipation capacities. Furthermore, the proposed mechanics-based equations can predict the moment capacity of the connection with sufficient accuracy.
