TL;DR: In this paper, the authors introduce the concept of modal reliability, which is defined as the amount of uncertainty the system can tolerate before failure, i.e., a system is reliable if it can tolerate a large amount of unknownness before failure can occur.

TL;DR: In this paper, structural system reliability is tackled by Monte-Carlo integration using descriptive sampling instead of the random sampling in the crude Monte Carlo procedure as well as in the importance sampling procedures.

TL;DR: In this paper, the authors studied the stochastic response of nonlinear nonhysteretic single-degree-of-freedom oscillators subject to random excitations with independent increments, where the state vector made up of the displacement and the velocity components becomes a Markov process.

TL;DR: In this paper, an approach to determining appropriate design load values for structural design situations other than the full design-life is presented, which may be especially useful for the design of structures exposed to environmental loadings such as wind, snow and earthquake for relatively short exposure periods.

TL;DR: In this article, an assessment procedure based on structural system reliability principles was developed for highway bridges with concrete or composite decks, which concentrates on the ultimate flexural limit state of slabs and takes account of the fact that the failure of the structure is dependent on the combination of the applied loads, their variability, both spatial and in amplitude, and on the variability of geometric and material properties.

TL;DR: In this paper, the influence of the order of autoregression and the number of sample points is investigated for the autoregressive method for simulation of wind histories, and the mean value, variance, and power spectra of the wind speed of the generated sample are assessed by comparison with the target parameters required.

TL;DR: In this paper, an approximate system reliability analysis method, including system effects and load duration effects, is used to study the lifetime behavior of wood floor and roof systems, based on the results from a simplified beam-spring model.

TL;DR: In this article, an efficient reliability method is proposed for space framed structures based on linearization of the mechanical behavior of the material, where the elastic-plastic behavior of material is piecewise linearized by a plastic criterion taking into account the interaction of internal forces.

TL;DR: In this article, a new mathematical model of the acceptance control of concrete was suggested and on the basis of the model Monte Carlo simulation was performed, the problems to determine within and between batch coefficients of variation, to specify minimum required strength of concrete, to check feasibility of batch rejection using minimum experimental value of concrete strength, to verify experimentally the GOST 18105-86 rules for acceptance controlling of concrete were stated and solved.

TL;DR: In this article, the authors considered the time series of the pressure measurements at a certain pressure tap is taken to be a statistically stationary process with a defined mean value and variance, and derived the theoretical distribution of the maximum exceedence over a given duration of time.
