AIDJEX Results on Arctic Ice Mechanics
Over the last decade the Arctic Ice Dynamics Joint Experiment (AIDJEX) at the University of Washington has been modeling the air-ice-water regime of the Arctic and checking the results...

Stochastic Analysis of Yielding System
The probability distribution of the instantaneous incremental yield of an inelastic system is characterized in terms of a conditional probability and average rate of crossing. The detailed...

Elastic-Plastic Slabs on Elastic Foundation
A method of analysis and design of rectangular and circular elastoplastic, reinforced concrete, and slabs resting on a Winkler-type foundation is proposed in this paper. The method is...

The aim of this note is to extend the Prager-Shield cost-gradient method from optimal plastic design to optimal elastic permissible stress design. It is shown in the context of beams having...

Autostress Principles for Beams with Web Openings
Recently, the concept of autostresses was developed for unifying the elastic and plastic design of steel structures, autostresses being the residual stresses that occur during the initial...

Inelastic Response to Site-Modified Ground Motions
A building with a period equal to that of a site may be more susceptible to yielding during a moderate earthquake, but the larger yielding during a major earthquake is much the same as...

Ultimate Load Carrying Capacity of Steel Arches
The spatial elasto-plastic behavior of steel arches is investigated in the case where they collapse due to inelastic lateral instability producing flexural-torsional deformations towards...
