The first-order reliability method (FORM) is used to estimate the first-excursion probability of uncertain structures subjected to deterministic dynamic loads. An algorithm is developed...

Risk Based Structural Optimization
Risk based structural optimization problems for structural systems are formulated on basis of a so-called risk index. The risk index is defined as a consequence modified reliability index...

Critical Buckling Load Statistics of an Uncertain Column
The objective of this paper is to examine the statistics of the buckling load of a column with uncertain material properties. The elastic modulus is assumed to be a random process that...

Bridge Overloading Criteria
Considerable concern is being expressed by the public and government agencies over the deteriorating state of the country's infrastructure. At the same time, there is a general feedling...
