A Stable Method for Time-dependent Reliability Analysis
(2023)The problem of time-dependent reliability arises in engineering practice due to the degradation of structural material properties over time and the involvement of time-dependent loads. For time-dependent reliability analysis ... -
A closed-form non-stationary solution of fractional systems with order 1/2 subjected to stochastic excitation
(2023)Abstract: This paper develops a novel method for determining a closed-form non-stationary stochastic response of linear systems with fractional derivative order 1/2 and subjected to stationary stochastic excitation. This ... -
Stacked Sparse Autoencoders and Classical Artificial Neural Networks for the Inverse Uncertainty Quantification of Dynamic Engineering Systems Models
(2023)In the analysis of complex, safety-critical dynamic engineering systems, it is necessary to provide the uncertainty quantification of the outputs of the mathematical models (and the corresponding computer codes) used to ... -
Response of latticed shell subjected to uniform and spatially varying spectrum-matched seismic ground motion excitations
(2023)Seismic design of latticed shell structures requires the use of structural analysis results obtained by using the design spectrum-matched ground motion records. As finding such records from the database of the actual ... -
A COMPARATIVE STUDY ON SAMPLING BASED ALGORITHMS FOR NETWORK RELIABILITY ASSESSMENT
(2023)Infrastructure networks, such as electrical power grids, transportation and water supply systems, support critical societal functions of society. Failures of such networks can have severe consequences, and quantification ... -
Statistical-based model development with surrogate rainfall fields and its use to assess typhoon rain hazard for coastal region of mainland China
