Elastic Initial and Post-local Buckling of Profiled through Girders

An experiment investigating the elastic local buckling response of trough girders composed of thin profiled steel sheeting has been undertaken Beam tests were performed to promote initial local buckling in a region of constant moment in the elastic range of structural response. The results of the experiments were compared with an elastic complex semi-analytical finite strip method of analysis, ...

Robust Truss Topology Design via Semidefinite Programming

We present and motivate a new model of the truss topology design problem, where the rigidity of the resulting truss with respect both to given loading scenarios and small “occasional” loads is optimized. It is shown that the resulting optimization problem is a semidefinite program. We derive and analyze several equivalent reformulations of the problem and present illustrative numerical examples.

Improving Solutions to the Truss Topology Design Problem with Alternating Convex Optimization

In the design of a mechanical structure, we’re interested in finding a general layout of the structure’s supporting frame that best supports some anticipated design loads. Often, the design of such supporting frames are addressed in ad-hoc ways, such as by complicated domain-specific heuristics [TTG05, DG01]. Our project targets the problem of designing a truss–a collection of bars rigidly atta...

Design Requirements for Plate Girders with Bolted Transverse Stiffeners

The web of plate girders in bridges are usually reinforced by welded transverse stiffeners in order to improve their shear capacity.Due to problems associated with field welding and fatigue, welded stiffeners are not suitable for retrofitting existing bridges. Bolted stiffeners are a practical alternative for strengthening girders that are expected to experience shear stress in excess of their ...
