Abstract
The presented thesis studied proposed a novel procedures that was implemented todevelop a Structural Health Monitoring (SHM) technique as non-destructive tests that canbe applied to detect damage, localization and quantification of civil structures. Thistechnique based on investigations of dynamic characteristics of the structures to detect thedamages through their operational conditions of service life. The proposed procedure wasbuilt using Artificial Intelligence Technique (AIT) under concept of the methods of damagedetection based on updating FE model using heuristic optimization methods. The proposedSHM procedure Using Simulated Annealing heuristic optimization methos was shortenedto "SHMUSA-procedure". The SHMUSA-procedure was verified on four types of steelstructural models; simply supported overhang beam; grid bridge, Verendeel bridge andMulti-storey building model to prove reliability, efficiency and robustness under variousdynamic behaviours. The SHMUSA-procedure was adopted t...he changes in dynamiccharacteristics, natural frequency and normalized mode shape vector, which are extractedfrom experimental modal analysis and estimated from numerical modal analysis of thedamage scenario for structural models. and their characteristics, location and severity,.The experimental testing is implemented using simulation of ambient vibrationmeasurements by exciting the structural models by shaker device using generated vibrationsignal. The dynamic response, output only, of the structural models are recorded using 8-accelerometers and 8-channel acquisition device. Experimentally, the modal properties ofthe structural models are extracted by ARTeMIS extractor software using FrequencyDomain Decomposition (FDD) technique by peak picking method. The numericalsimulation of structural models are modeled in Finite Element Model (FEM) using ANSYSpackage software by ANSYS Parametric Design Language (APDL). Numerically, themodal properties of structural models are estimated by ANSYS software using blockLanczos method of dynamic modal analysis for isotropic elastic linear structural modelstype. The Finite Element Analysis (FEA) is performed using three element types in the FEmodels, Beam4, Shell63 and Mass21, to analyze the four structural models...
