Structural Engineering Distinguished Professor Chia-Ming Uang recently won the “Best Paper” award in Analysis and Computation in the 2022 ASCE Journal of Structural Engineering for his paper titled “A Procedure for Assessing Low-Cycle Fatigue Life of Buckling-Restrained Braces”.

The study aimed to assess the fatigue life of Buckling-Restrained Braces (BRBs) after seismic events. Researchers conducted tests on 18 full-scale BRBs and developed two low-cycle fatigue models based on 11 symmetric, constant-amplitude tests. An assessment procedure combining the proposed fatigue models, the rainflow cycle counting method, and the Miner’s damage index was proposed to predict the fatigue life of BRBs subjected to random cyclic loading histories, which was validated by the variable-amplitude test results.
