A Modified Wavelet Energy Rate Based Damage Identification Method for Steel Bridges

Abstract: Strain is sensitive to damage, especially in steel structures. However, a traditional strain gauge does not t bridge damage identi cation because it only provides the strain information of the point, where it is set up. While traditional strain gauges su er from drawbacks, a long-gage FBG strain sensor is capable of providing the strain information of a certain range, in which all the damage information within the sensing range can be re ected by the strain information provided by FBG sensors. The wavelet tran… Show more

“…The deck has a uniform cross section as shown in Figure 2b. The area is 5.64 m 2 , and the weak-axis second moment of inertia is 3.58 m 4 . On the other hand, the two piers have the same circular cross-section with radius 1 m and moment of inertia 0.785 m 4 .…”

“…An artificial neural network (ANN) is a machine learning algorithm used to solve advanced nonlinear problems such as handwriting or speech recognition [36][37][38][39][40][41][42][43][44]. Neural networks connect computational nodes together to form a singular network, where each computational node is performing a calculation on its input and outputting the result to all outgoing connections.…”

“…A toolbox for computing the parameters of BWBN hysteresis model using multi-objective optimization evolutionary algorithms was also developed by SourceForge, an Open Source community (Bouc Wen Baber Noori Model of Hysteresis, Source Forge). Foliente showed Bouc-Wen-Baber-Noori (BWBN) model could produce previously observed inelastic behavior of wood joints and structural systems using BWBN smooth hysteresis model (Foliente, 1995;Zhao et al, 2017a,b;Noori et al, 2018). Deb et al developed a toolbox that identifies structural parameters of Bouc-Wen-Baber-Noori hysteresis model through a noval multi-objective optimization evolutionary algorithms (MOBEAs) (Deb et al, 2002;Deb, 2013).…”
