Dynamic load identification for stochastic structures based on Gegenbauer polynomial approximation and regularization method
TL;DR: Based on the Gegenbauer polynomial expansion theory and regularization method, an analytical method is proposed to identify dynamic loads acting on stochastic structures in this article, which is expressed as functions of time and random parameters in time domain and the forward model of dynamic load identification is established through the discretized convolution integral of loads and the corresponding unit-pulse response functions of system.
Journal ArticleDOI
First and second order approximate reliability analysis methods using evidence theory
TL;DR: The first order approximate reliability method (FARM) and second order approximations (SARM) are formulated based on evidence theory and can significantly improve the computational efficiency for evidence-theory-based reliability analysis, while generally providing sufficient precision.
Journal ArticleDOI
An uncertain structural optimization method based on nonlinear interval number programming and interval analysis method
TL;DR: In this paper, a nonlinear interval number programming method is proposed to solve uncertain structural problems based on an interval analysis method and an intergeneration projection genetic algorithm is employed to seek for Pareto optimum of the uncertain problem.
Journal ArticleDOI
An efficient method to reduce ill-posedness for structural dynamic load identification
TL;DR: In this article, an efficient interpolation-based method is proposed to reduce ill-posedness availably and identify dynamic load stably, where the load history is discretized into a series of time elements, and the load profile in each time element is approximated through interpolation functions.
