1. 21. Damage detection on railway bridges using Artificial Neural Network and train induced vibrations

   University essay from KTH/Bro- och stålbyggnad

   Author : Jiangpeng Shu; Ziye Zhang; [2012]
   Keywords : Damage detection; Railway Bridge; Dynamic Response; high-speed trains; Statistical Property; Artificial Neural Network ANN ;

   Abstract : A damage detection approach based on Artificial Neural Network (ANN), using the statistics of structural dynamic responses as the damage index, is proposed in this study for Structural Health Monitoring (SHM). Based on the sensitivity analysis, the feasibility of using the changes of variances and covariance of dynamic responses of railway bridges under moving trains as the indices for damage detection is evaluated.

3. 22. Data Processing Algorithms in Wireless Sensor Networks får Structural Health Monitoring

   University essay from KTH/Bro- och stålbyggnad

   Author : Nigatu Mitiku Danna; Esayas Getachew Mekonnen; [2012]
   Keywords : Bridge; FFT; Modal Analysis; Monitoring; Natural Frequency; Peak Picking; Structure; Wireless Sensor.;

   Abstract : The gradual deterioration and failure of old buildings, bridges and other civil engineering structures invoked the need for Structural Health Monitoring (SHM) systems to develop a means to monitor the health of structures. Dozens of sensing, processing and monitoring mechanisms have been implemented and widely deployed with wired sensors. READ MORE

4. 23. Design and Research of Structural Health Monitoring System for Stayed Cable Bridge Based on LabWindows/CVI

   University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

   Author : Zhang Ping; [2008]
   Keywords : LabWindows CVI; Stayed-cable bridge; Structural health monitoring system;

   Abstract : The thesis mainly research how to design the health monitoring system for stayed-cable bridge based on LabWindows/CVI, which includes the methods of developing the system and all kinds of theories and technologies applied in the design process. In accordance with the function modules of the system, the design process and used theoretical methods of each module are described, and the application applicability of each function module is verified with demonstrations or experiment.

5. 24. Damage Assessment in Thin Materials : Finite Element Investigation

   University essay from Blekinge Tekniska Högskola/Avdelningen för maskinteknik

   Author : Mirza Mohammed Yousuf Baig; [2006]
   Keywords : NDT; Finite Element; ABAQUS; Damage Assessment; Eigenvalue; Stiffness;

   Abstract : This thesis describes the process of detection, and if possible, also localization of the damage in non structural sheet-like materials. Simulation and analysis is carried out in ABAQUS with a FE model that has the same dynamic characteristics as the corresponding real material. READ MORE
