Abstract: An integrated strategy for sizing and shape optimization of truss structures, taking buckling constraints implicitly into truss design, is demonstrated here. Because the associated objective functional is not convex, a ...

Abstract: Pipelines are one of the most important lifeline facilities that play a vital role in maintaining the public safety and economic wellbeing of a nation. They traverse over a large area with nonuniform soil conditions and ...

Abstract: When traversing through an active strike-slip fault, buried pipelines may be subjected to permanent ground deformation (PGD), causing large strains in the pipeline during an earthquake. The presence of bends near the ...
