This book was released on 1988 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: "Damage analysis models based on equivalent modal parameters are used to identify the serviceability limit state for structures subjected to earthquake loads. A model for the analysis of seismic structural damage consists of a finite number of numerical indicators (damage indices) and of a procedure for their computation. A structure exhibits a nonlinear behavior when it experiences an earthquake. Nonetheless, an equivalent linear structure can be defined. Damage indices can be defined from the vibrational parameters of the equivalent linear structure considered. In the first place, it is shown that the problem of identification of the serviceability limit state is equivalent to the problem of detection of seismic structural damage. A limit state can be defined as a surface in the space of the damage indices relative to the model considered. Experiments on small-scale models are analyzed to obtain an analytical definition of the serviceability limit state. Since many uncertainties are present in any damage analysis problem, a probabilistic definition is obtained, in terms of the probability that the structure considered is damaged after the seismic event. Finally, records from large-scale models and full-scale structures are analyzed. The model proposed performs very well in detecting seismic structural damage."--Abstract

Available in PDF, EPUB and Kindle. Book excerpt: Over a period of several years the field of probabilistic mechanics and com putational mechanics have progressed vigorously, but independently. With the advent of powerful computational hardware and the development of novel mechanical techniques, the field of stochastic mechanics has progressed in such a manner that the inherent uncertainty of quite complicated systems can be addressed. The first International Conference on Computational Stochastic Mechanics was convened in Corfu in September 1991 in an ef fort to provide a forum for the exchanging of ideas on the current status of computational methods as applied to stochastic mechanics and for identi fying needs for further research. The Conference covered both theoretical techniques and practical applications. The Conference also celebrated the 60th anniversary of the birthday of Dr. Masanobu Shinozuka, the Sollenberger Professor of Civil Engineering at Princeton University, whose work has contributed in such a great measure to the development of Computational Stochastic Mechanics. A brief sum mary of his career and achievements are given in the Dedication. This book comprises some of the papers presented at the meeting and cov ers sections on Theoretical Reliability Analysis; Damage Analysis; Applied Reliability Analysis; Theoretical Random Vibrations; Stochastic Finite Ele ment Concept; Fatigue and Fracture; Monte Carlo Simulations; Earthquake Engineering Applications; Materials; Applied Random Vibrations; Applied Stochastic Finite Element Analysis, and Flow Related Applications and Chaotic Dynamics. The Editors hope that the book will be a valuable contribution to the grow ing literature covering the field of Computational Stochastic Mechanics.

This book was released on 2020-04-22 with total page 266 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nowadays, numerical computation has become one of the most vigorous tools for scientists, researchers and professional engineers, following the enormous progress made during the last decades in computing technology, in terms of both computer hardware and software development. Although this has led to tremendous achievements in computer-based structural engineering, the increasing necessity of solving complex problems in engineering requires the development of new ideas and innovative methods for providing accurate numerical solutions in affordable computing times. This collection aims at providing a forum for the presentation and discussion of state-of-the-art innovative developments, concepts, methodologies and approaches in scientific computation applied to structural engineering. It involves a wide coverage of timely issues on computational structural engineering with a broad range of both research and advanced practical applications. This Research Topic encompasses, but is not restricted to, the following scientific areas: modeling in structural engineering; finite element methods; boundary element methods; static and dynamic analysis of structures; structural stability; structural mechanics; meshless methods; smart structures and systems; fire engineering; blast engineering; structural reliability; structural health monitoring and control; optimization; and composite materials, with application to engineering structures.
Download or read book Aging Shaking and Cracking of Infrastructures written by Victor E. Saouma and published by Springer Nature. This book was released on 2021-04-13 with total page 1153 pages. Available in PDF, EPUB and Kindle. Book excerpt: This self-contained book focuses on the safety assessment of existing structures subjected to multi-hazard scenarios through advanced numerical methods. Whereas the focus is on concrete dams and nuclear containment structures, the presented methodologies can also be applied to other large-scale ones. The authors explains how aging and shaking ultimately lead to cracking, and how these complexities are compounded by their random nature. Nonlinear (static and transient) finite element analysis is hence integrated with both earthquake engineering and probabilistic methods to ultimately derive capacity or fragility curves through a rigorous safety assessment. Expanding its focus beyond design aspects or the state of the practice (i.e., codes), this book is composed of seven sections: Fundamentals: theoretical coverage of solid mechnics, plasticity, fracture mechanics, creep, seismology, dynamic analysis, probability and statistics Damage: that can affect concrete structures, such as cracking of concrete, AAR, chloride ingress, and rebar corrosion, Finite Element: formulation for both linear and nonlinear analysis including stress, heat and fracture mechanics, Engineering Models: for soil/fluid-structure interaction, uncertainty quantification, probablilistic and random finite element analysis, machine learning, performance based earthquake engineering, ground motion intensity measures, seismic hazard analysis, capacity/fragility functions and damage indeces, Applications to dams through potential failure mode analyses, risk-informed decision making, deterministic and probabilistic examples, Applications to nuclear structures through modeling issues, aging management programs, critical review of some analyses, Other applications and case studies: massive RC structures and bridges, detailed assessment of a nuclear containment structure evaluation for license renewal. This book should inspire students, professionals and most importantly regulators to rigorously apply the most up to date scientific methods in the safety assessment of large concrete structures.

Download or read book Finite element Based Damage Detection Methods for Nonlinear Reinforced Concrete Structures written by Ai-Lun Wu and published by . This book was released on 2012 with total page 172 pages. Available in PDF, EPUB and Kindle. Book excerpt: An objective of the structural health monitoring system is to identify the state of the structure and to detect its damages after a major event, such as a strong earthquake. The ability to assess the state of the structure, including its damages, immediately after a severe event, will allow a rapid assessment of the civil infrastructures for the post-event emergency responses, rescues and management, to guarantee the safety operations of these structures. Hence, intensive research has been conducted for detecting structural damages based on vibration data measured from sensors. To date, unfortunately, practical and effective damage identification techniques based on the finite-element formulation remain to be developed for large-scale linear and nonlinear structures, in particular nonlinear hysteretic reinforced concrete (RC) structures. The objective of this research is to develop an innovative, practical and efficient identification method based on the finite-element formulation, system condensation technique, and the event response data, such as the seismic response data, for applications to structural health monitoring systems. The innovative research will be capable of quantitatively determining the damage severity (time varying stiffness degradations) and locations of damages at element level. The developed new and efficient finite-element based methodology for structural damage detection would be: (1) applicable to linear and non-linear structures. (2) capable of identifying and tracking the structural damages using a minimum number of sensors, (3) capable of detecting local damages at element level, and (4) ready for practical applications to the health monitoring of complex structures. In addition to the theoretical/numerical development, experimental test data using large-scale linear and nonlinear structures, i.e. 1/3-scaled two-story RC frame and 1/2-scaled one-story two-bay RC frame, obtained from the National Center for Research on Earthquake Engineering (NCREE), Taiwan, will be used to verify the proposed innovative structural damage detection technique.
