Abstract: In recent years, considerable attention has been paid to research and development of structural control devices, with particular emphasis on alleviation of wind and seismic response of buildings and bridges. In both areas, ...

Abstract: This paper presents a semi-implicit integration algorithm for random vibration problems that is appropriate for analyzing large structures, nonlinear hysteretic systems, and structural control problems. This semi-implicit ...

Abstract: A method to determine statistical moments of time to first passage of a simple oscillator, incorporating the modified Bouc hysteresis model, has been developed. A generalized Pontriagin‐Vitt equation is formulated from ...

Abstract: Crack propagation analysis is a major task in the design and life prediction of fatigue‐critical structures, yet experimental tests indicate that fatigue crack propagation involves a large amount of statistical variation ...

Abstract: The reliability of uncertain single degree‐of‐freedom linear and nonlinear systems subjected to broadband random excitation is examined. A robust Petrov‐Galerkin finite element solution for the reliability of deterministic ...

Abstract: A one-dimensional stochastic micromechanical model is developed for brittle materials subjected to monotonic uniaxial loading. The material is represented by a set of brittle linear-elastic springs of equal stiffness that ...

Abstract: Under extreme environmental loadings such as winds, waves, and earthquakes, civil engineering structures are known to undergo large vibration responses, often resulting in severe damage. Recent developments in active ...

Abstract: A “smart” base isolation strategy is proposed and shown to effectively protect structures against extreme earthquakes without sacrificing performance during the more frequent, moderate seismic events. The proposed smart ...

Abstract: One of the most successful means of protecting structures against severe seismic events is base isolation. However, optimal design of base isolation systems depends on the magnitude of the design level earthquake that is ...
