Expectation Ratio Versus Probabilityquences of a failure with a given probability of occurrence, as well as the expenses required to reduce such probability, can much vary from a structural system to another, it is advocated that the design of structural systems be based, instead, on the consideration of the ratio of the expectation o

Application of Probabilistic Structural Modelling to Elastoplastic and Transient Analysiseam to a moving load is reported. The probabilistic structural analysis methodology is based on a unique integration of a specially developed finite element code together with a probability integration method capable of providing accurate predictions of the cumulative probability distribution for a

Reliability-Based Shape Optimization Using Stochastic Finite Element Methodsent years, see e.g. Frangopol [4], Murotsu, Kishi, Okada, Yonezawa . Taguchi [9] and Sørensen [14]. In probabilistically based optimal design of structural systems some of the quantities used in the modelling are modelled as stochastic variables. The stochastic variables are usually related to the s

Identification of Autoregressive Process Model by the Extended Kalman Filter) or moving average (MA) models that can be used in the idealization of earthquake ground motions, since by these models not only sample input waves but also response waves may be recursively simulated and consequently it has been found that they are effective models used in the field of stochastic

The Effect of a Non-Linear Wave Force Model on the Reliability of a Jack-Up Platform the jack-up is used to determine a non-linear relation between the wave height and the maximum leg stresses. The non-linearities follow from the use of Morison’s formula, Stoke’s fifth order wave theory and integration of wave forces to the actual water surface. Loads due to current, wind and gravi
