ABSTRACT
In this paper, a practical non-destructive evaluation approach to determine the stress of inservice structural steel members using Lcr waves
1 INTRODUCTION
Stress is one of the main factors determining the design and analysis of steel structures. The effective and reliable measurement of stress can provide useful information that allows the safety of existing structures to be evaluated. For that reason, stress analysis is a compulsory stage in the process of design and evaluating steel structures. However, traditional stress measurement methods, such as the sectioning method (Shadley et al. 1987), hole-drilling method (Bateman et al. 2005), strain gauge method (Watanabe et al. 2010) and diffraction methods (Monin et al. 2014, Seok-Hoon et al. 2009), cannot measure stress of in-service structural steel members accurately and reliably. This may increase the risk of structural failure.
