The most common approach to assess the safety of a bridge is load rating. However, this approach cannot quantify the bridge safety in probabilistic terms or fully quantify the structural risk to the bridge. Reliability methods have become an increasingly popular and gradually accepted approach to assess the safety of structures. These methods account for the randomness and correlation of all re...

According to ISO 2394, structures shall be designed, constructed and maintained in such a way that they are suited for their use during the design working life in an economic way. To fulfil this requirement one needs insight into the risk and reliability under expected and non-expected actions. A key role in this respect is played by the structural reliability analysis (SRA). In this paper the ...

We probe the reliability of monopile support structures designed to support industrial scale turbines along the coastal United States using stochastic models for the wind and wave loadings, and representations of the uncertainty associated with soil properties. The turbine support structure investigated is that promulgated by the National Renewable Energy Laboratory as typical of a monopile sup...

One of the critical design driving load cases for modern large onshore/offshore wind turbines is power production in extreme turbulence. According to the IEC 61400-1 edition 3 design standard, the normal production extreme loads are extrapolated and compared to the extreme loads obtained under extreme turbulence input. This study shows that using a probabilistic approach and the first order rel...

objectives: the present research aims to prepare an iranian police job satisfaction inventory (ipjsi) by using confirmative factor analysis as well as to evaluate the validity and reliability of it. method: a group consisting of 2933 iranian police employees chosen by stratified random sampling method from a number of police departments throughout the country completed the ipjs inventories. val...

The generating function approach is an important tool for performance assessment in multi-state systems. Aiming at strength reliability analysis of structural systems, generating function approach is introduced and developed. Static reliability models of statically determinate, indeterminate systems and fatigue reliability models are built by constructing special generating functions, which are...

It is very difficult to built reliability design model of structural parts working in a complex and uncertain environment because of their dynamic time-dependent characteristic, an intelligent method of reliability analysis based on integration algorithm is presented in this paper, RBFNN and finite element analysis combined with Monte Carlo numerical simulation is integrated to improve simulati...
