Intelligent structures 2 : monitoring and control by International Workshop on Intelligent Structures( Book )
11 editions published in 1992 in English and German and held by 86 libraries worldwide
Construction is the largest industry in the world, yet technology to monitor and maintain the health of building and structural systems under natural and man-made loadings has only just begun to receive the attention that it deserves. Real time sensing, monitoring and control of structural systems is now feasible, made possible by recent developments in analytical and numerical modelling, and new technologies and hardware. The Intelligent Systems Workshop was held to promote information exchange, research co-operation and introduction of new ideas and concepts. Investigators from the US, Italy, Japan and other Western European countries gave presentations and participated in group discussions.; The book covers the following new areas for further development in the utility and serviceability of structural systems: non-destructive tests to assess the state of damage caused by natural forces such as earthquake and wind; improvement of passive, active and hybrid devices used to suppress excessive structural vibration under seismic and wind conditions; development of knowledge-based systems and a neural network that can be trained to perform more effectively on structure control; application of more advanced sensor devices, often loaded in a mobile laboratory, for timely information gathering; and development of intelligent materials, buildings, tunnels, and highway bridges with capacity to detect negative internal changes in performance due to earthquakes, extreme winds and other natural hazard conditions. As the modern world begins to depend more and more on development in high technology this book will help ensure that structural engineering benefits significantly

Investigation of alternative seismic design procedures for standard buildings by Kevin R Collins( Book )
3 editions published in 1995 in English and held by 6 libraries worldwide
The seismic design provisions of most building codes in the United States specify ground motion parameters for various regions of the country and provide simple formulas to determine a distribution of lateral forces for which the structure should be designed. The simple formulas typically involve the use of one or more "factors" to account for anticipated inelastic behavior of the structure, relative importance of the structure, and site soil effects. Although these code provisions are very simple to use, they oversimplify a complex problem and are based on many implicit assumptions which many designers may not appreciate. Furthermore, the reliability of the final design is not known. An alternative design and analysis procedure, in which the underlying assumptions are more clearly defined and which provides a more uniform level of reliability in the final design, is presented. The procedure requires the designer to consider two levels of earthquake excitation. "Equivalent" single-degree-of-freedom models and uniform hazard response spectra are used to evaluate structural performance. Deterministic design-checking equations are derived based on displacement-based performance criteria which are expressed in probabilistic terms. The deterministic design equations account for the uncertainty in predicting site soil effects, the uncertainty in seismic hazard, and the approximate nature of the simplified models of the structure through the use of design factors. The goal of the alternative procedure is to enable designers to achieve code-specified target performance objectives for moderate and severe levels of earthquake excitation

Stochastic finite element analyses of uncertain nonlinear plane trusses under random excitations by Rwey-Hua Cherng( Book )
2 editions published in 1992 in English and held by 4 libraries worldwide
A method of stochastic finite element analysis is developed in this study to solve for the response statistics and reliability of nonlinear truss structures with uncertain system parameters under random excitations. Emphasis is on structural nonlinear behavior due to both large deflection and inelastic deformation. The constitutive law is based on an explicit differential equation model, and the model parameters are determined in terms of material property constants according to plasticity theory. Random excitations are modeled as Gaussian filtered white noises, whereas uncertain system parameters are modeled as either random fields or random variables. Based on a total Lagrangian finite element formulation, a set of stochastic nonlinear equations of motion is obtained. A stochastic equivalent linearization method, in conjunction with a perturbation method, is then developed to solve for the total response statistics. A second order asymptotic method is proposed to evaluate the overall structural reliability. Numerical studies indicate that the proposed method yields accurate results with much less computer time compared with the Monte-Carlo simulation method. It is found that the system uncertainties make a significant contribution to the total response statistics as well as to the overall probability of failure. Dominant system parameters are also identified by non-dimensional response sensitivity analyses

Modeling of nonstationary earthquake ground motion and biaxial and torsional response of inelastic structures by Chin-Hsun Yeh( Book )
2 editions published in 1989 in English and held by 3 libraries worldwide
A systematic way to analyze the response of inelastic structures under bi-directional random excitations is developed. Most of the system and excitation characters have been considered, e.g., hysteretic behavior of restoring force, biaxial interaction, torsional response and degradation of the structure, and nonstationary behavior of ground excitation. A new stochastic ground motion model is proposed in which both intensity and frequency content are functions of time. Corresponding methods for estimating the model parameters based on actual earthquake records are also given. The proposed ground motion model can be efficiently applied to simulations as well as analytical solutions of random vibration and reliability studies for inelastic structures. Responses of single-mass inelastic systems and three-story space frames, with or without deterioration, under bi-directional non-stationary ground excitations are investigated via an equivalent linearization method and Monte Carlo simulations. The results show that (1) the equivalent linearization method predicts the response statistics quite well except for r.m.s. displacement, which can be improved by the proposed semi-empirical equation; (2) the time-varying frequency content of ground excitation has significant effects on the response of inelastic structures, especially when the excitation dominant frequencies are close to the structural pre-yielding natural frequency; (3) biaxial and torsional response may become significant in an asymmetric structure

Method of seismic reliability evaluation for moment resisting steel frames by Dimitris F Eliopoulos( Book )
2 editions published between 1989 and 1991 in English and held by 3 libraries worldwide
A method for the evaluation of structural performance of moment resisting steel frames in future earthquakes is developed in this study. With this approach, one can evaluate the probability of failure (exceedance of a limit state) of such frames during their design lifetime. A seismic hazard analysis is carried out in which the characteristics of ground motion at a site are identified and the uncertainties associated with source and ground motion parameters are quantified. Earthquake excitation is modeled by a nonstationary random process with time-varying amplitude and frequency content. The parameters of the model are identified from available seismological and geological information at the site where the structure is located. A strong-column-weak-beam model is proposed in this study for moment resisting steel frames which reduces the number of degrees of freedom in the analysis and produces the response of these frames with computational efficiency and good accuracy. A random vibration analysis is performed based on the equivalent linearization method and the response statistics are evaluated for a given set of ground motion parameters. The conditional probability of failure of the frame is then derived using these statistics. A fast integration technique based on the first order reliability method is finally used to evaluate the probability of failure during the design lifetime of the structure. The robustness of the proposed method is demonstrated in the numerical examples throughout this study. The method can be used in assessing the risk implied in current earthquake resistant design practice, and in developing reliability-based code procedures
