Low-cycle fatigue performance and allowable fatigue damages of BRRP seismic dampers

Abstract

This paper presents a study on a high-performance seismic damper termed Buckling Restrained Rippled Plate (BRRP) damper. Focused in this paper is the establishment of the low-cycle fatigue performance of BRRPs as the ultimate limit state based on a series of experimental and numerical studies. In addition, the allowable fatigue damages of BRRPs that are so designed as to withstand three consecutive Level 2 earthquakes are introduced in order to verify the serviceability limit state.
