Abstract

Title: Ultra-Low Cycle Fatigue and Fracture in Steel Structures (NEES-2005-0096)

Year Of Curation: 2011

Description: During earthquakes structural elements such as bracing members undergo a phenomenon called Ultra-Low Cycle Fatigue (ULCF), which is characterized by very few (lack of suitable micro-scale models to simulate ULCF and the computational requirements necessary implement the models for studying large structural components. This research aims to (1) identify and quantify the underlying failure mechanisms of earthquake-induced ULCF, (2) develop and implement models to simulate ULCF in steel structures (3) conduct large scale subassembly tests at earthquake loading rates to verify and demonstrate the models (4) apply the ULCF models to develop practical guidelines and recommendations for earthquake resistant design.
