Low‐Cost Friction‐Based Force‐Limiting Connection With Reduced Sensitivity to Machining Tolerances and Accelerated Repairability

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper presents a novel yet practical friction‐based structural component design for low‐damage earthquake‐resistant structures. The proposed connection design is based on a conventional slotted‐bolted configuration with the novelty being the use of loose steel washer plates to establish the friction‐sliding interface.
