Reliability Analysis of Structures with Interval Uncertainties under Stochastic Excitations
In this paper, an approach able to evaluate approximate explicit expressions of interval response statistics and structural reliability of randomly excited linear structures with uncertain parameters is addressed. The excitation is modeled as a stationary Gaussian random process. Uncertainty in structural parameters is handled by applying the interval model. Under the assumption of independent ...
متن کاملReliability Sensitivity Estimation of Linear Systems under Stochastic Excitation
The objective of this paper is presenting an approach for reliability sensitivity estimation of linear structural systems subject to dynamical excitation characterized as a Gaussian process. The paper represents an extension of some ideas proposed previously in the context of sensitivity analysis. Novel aspects include the use of the Bootstrap method for assessing the error associated with the ...
متن کاملOn the analysis of nonlinear systems under stochastic excitations
The work presented here addresses the evaluation of the stochastic response of nonlinear FE-systems with a relatively large number of degrees of freedom (DOF’s) under random excitation. In order to perform a realistic analysis for such systems, FE-models with nonlinearities are generally considered. Most of the available analytical and numerical methods to calculate the stochastic response are ...
متن کاملDynamic Reliability Analysis of Mega-Sub Isolation System Under Random Ground Motion
Numerical example shows that when the damping ratio of the isolation device is given, the overall reliability of the structure increases at first then decreases with increased frequency ratio, when the frequency ratio is constant, the overall reliability of the structure increases with increased damping ratio. In addition, compared to the aseismic system, the overall reliability of the mega-sub...
متن کاملEvaluation of the Seismic Response of Single-Story RC Frames under Biaxial Earthquake Excitations
This paper summarizes the lessons learned from a full-scale test on two RC frame prototypes that have recently been tested on LNEC shaking-table using four pairs of biaxial synthetic ground motion records during 15WCEE Conference (2012). The reference structures are two single-story RC frames which are geometrically identical but with different reinforcement details. The simplified inelastic mo...
