Kalman Filtering of Versatile Restoring Systems,l iteration. By this method, a nonlinear versatile model applied to general hysteretic system may be identified in terms of the model’s parameters, at the stage of their convergency to optimal ones after weighted global iterations of the Extended Kalman filtering. The identification method is demons

Earthquake Failure Mechanism of Hysteretic Structures with Stress-Strain Based Modeling,inearity of an RC element is evaluated by using a so-called “fiber model” based on stress-strain relation. Accuracy of constitutive laws is examined from comparison of analytical and experimental moment-curvature relations. Failure mechanism is then examined with a damage index that includes effects

The Stochastic Response of Strongly Yielding Systems,nd-order and third-order equivalent linearization schemes are examined. It is shown that although these approximate techniques generally give acceptable results for second-order response statistics they fail to yield an accurate description of the nature of the response in the frequency domain. The

Active Stochastic Control of Seismic Structures, out using a standardized structural model under base excitation produced by the Earthquake Simulator at SUNY/Buffalo. Based upon computer simulations and experimental results, this paper presents a comparison of effectiveness of several optimal control algorithms using instantaneous optimal criteri

Stochastic Estimates of Nonlinear Dynamic Systems,l equations. Based on the theory of continuous Markov vector process, differential forms of conditional probability density functions given observations during a finite time interval are presented by making use of the Kolmogorov differential operators and innovations process. Differential forms of c

Importance Analyses for Upgrading Seismic Reliability of Large Scale Lifeline Networks, measures for specifying critical components in lifeline networks. For each measure the sequence that strengthens each component is defined for the upgrading of the seismic reliability of the total system. Lifeline components are assumed to fail because of ground liquefaction. The theory for fatigue
