TL;DR: In this paper, a detailed comparison of the studies dealing with either infrastructure sustainability or resilience presented in this paper leads to the conclusion that they have a vast number of similarities and common characteristics, such as they both combine structural analyses with social and economic aspects; they both rely on techniques for the life-cycle analysis and decision making; and both are in an early stage, where the academic world is trying to find the best way to promote the application of the scientific results among professional engineers and the industry.

TL;DR: In this paper, an experimental approach for the analysis of localized fatigue damage processes during fatigue testing of welded steel structures by thermographic investigations of thermomechanical coupling phenomena is presented.

TL;DR: In this paper, a simple fracture mechanics model was proposed to predict the fatigue life of reinforced steel plate with prestressed carbon-fiber-reinforced polymer (CFRP) laminates.

TL;DR: In this article, the surface residual stresses at the weld toe are investigated before and after different loading conditions and for different steel grades, and the results of fatigue tests for butt welds and longitudinal stiffeners improved by high frequency hammer peening are presented.

TL;DR: In this paper, a statistical exploration is presented to assess the reliable magnitudes of post-yield properties in common structural grade steels, including the length of the yield plateau and the initial strain hardening tangent modulus.
