Download or read book System Identification for Structural Health Monitoring written by Izuru Takewaki and published by WIT Press. This book was released on 2012 with total page 273 pages. Available in PDF, EPUB and Kindle. Book excerpt: System identification (SI) techniques are important in reducing gaps between the constructed structural systems and their structural design models and in health monitoring for damage detection. Modal-parameter SI and physical-parameter SI are two major branches in SI.Special character of this book: (1) The physical-parameter SI method explained in this book requires only two accelerometers for measurement of records. Furthermore only a simple manipulation of Fourier transformation is required.(2) The stiffness and damping can be identified simultaneously.(3) The modal parameter SI can supplement or support the result by the physical-parameter SI method.(4) In place of usual low-pass or high-pass filter techniques, a novel noise-bias compensation method is explained. Because the noise itself is not known in many cases, the identification and elimination of noise is a tough problem.(5) A new technique of system identification is explained in the case where an inner vibration source exists.(6) The accuracy of the explained SI methods is examined by the actual recorded data.(7) MATLAB codes are available.This book is intended for Structural Engineers, Mechanical Engineers, Researchers, Graduate and undergraduate students.

Available in PDF, EPUB and Kindle. Book excerpt: This research study presents an approach to the problem of parameter estimation of finite element models of complex structural systems using measured response. The developed method computes the element, constitutive parameters of a finite element model of a structure by finding a constrained nonlinear minimum of the difference between the measured response of the real structure and the computed response of a finite element model of the structure. Constraints are used to bound the constitutive parameters. The proposed constrained nonlinear optimization problem is solved using a recursive quadratic programming (RQP) method. The constructed recursive quadratic programming algorithm is an attractive local optimization method that applies directly to problems with inequality as well as equality constraints, it is globally convergent, and it is amenable to large-scale computation. The RQP method is an iterative gradient search method that needs the gradient and Hessian of the loss function with respect to the unknown variables. A simple and straightforward method is developed to compute these sensitivities of the loss function with respect to the unknown variables. All the computations are in the element level. The method presented herein has been implemented as a general purpose parameter estimation program for structural systems. This program has all the flexibilities of a general purpose finite element package in that it can treat complex structures with different topologies, geometries and element types. It is suited to static, modal dynamic, or forced dynamic response, sparsely sampled in space, time, and state. It has a grouping scheme for considering the elements with the same constitutive parameters. Another feature of the developed package is to implement a priori knowledge about some of the constitutive parameters. Furthermore, it has strategies to compute initial values of the unknown variables for starting the iteration. Monte Carlo simulation is used to study the behavior of the developed parameter estimation method in the presence of noise in measurements. Extensive simulations are carried out for both the static and force dynamic cases. A case study, using real field measurements is presented for the modal dynamic case.

Available in PDF, EPUB and Kindle. Book excerpt: The papers in this volume provide an introduction to well known and established system identification methods for structural health monitoring and to more advanced, state-of-the-art tools, able to tackle the challenges associated with actual implementation. Starting with an overview on fundamental methods, introductory concepts are provided on the general framework of time and frequency domain, parametric and non-parametric methods, input-output or output only techniques. Cutting edge tools are introduced including, nonlinear system identification methods; Bayesian tools; and advanced modal identification techniques (such as the Kalman and particle filters, the fast Bayesian FFT method). Advanced computational tools for uncertainty quantification are discussed to provide a link between monitoring and structural integrity assessment. In addition, full scale applications and field deployments that illustrate the workings and effectiveness of the introduced monitoring schemes are demonstrated.
