Reliability of structural systems with correlated elements

Capacity of MIMO Wireless Systems, with Spatially Correlated Receive Elements

We present a general channel capacity model for a random A.W.G.N. channel in the presence of spatially correlated interference. We consider the case where the channel is random, and full rank and the number of receive elements is allowed to increase indefinitely within a given volume. We show that capacity of the channel does not increase indefinitely for densely packed elements. Moreover, the ...

Seismic Response of Building Structures with Sliding Non-structural Elements

Interaction between a structure under base excitation and heavy non-structural elements that it supports is significant in the seismic analysis and design of the structure. Heavy non-structural elements may slide/rock under base excitation, and this dynamic action affects the seismic behavior of the supporting structure. Hence, in this study, a numerical model was presented to describe the seis...

Reliability Analysis of Three Elements Series and Parallel Systems under Time-varying Fuzzy Failure Rate

Reliability is the most important performance issue in the engineering design process but in the real world problems, there are limitations for using the conventional reliability. Fuzzy logic has proved to be effective in expressing uncertainties in different fields, including reliability engineering. In this paper, For both the series and parallel systems composed of three identical or differe...

Structural Reliability and Its Sensitivity Analysis by Hybrid Markov Chain with Correlated Variables

In the practical engineering, to answer the small failure probabilities with correlated highdimensional variables, the subset simulation (SS) is combined together with the Monte Carlo simulation and importance sampling (IS) method. The samples from the probability density functions of the importance sampling are used to construct the intermediate failure events, by which the small failure proba...
