A New Design Method for Longitudinally Stiffened Plates
Longitudinally stiffened steel plates are becoming increasingly important in bridge design as the size and span of new bridges increase. An example is the Straits of Messina bridge, proposed to link Italy and Sicily, which will have a steel deck and steel towers. Now that most large bridges are part of design-build-finance contracts, in which the bid design phase determines the price of the project, it is especially important that the design process be as simple as possible to understand and implement rapidly. This paper proposes a unified design method for plates, with or without transverse stiffeners, that avoids some of the limitations, shortcomings or anomalies that engineers find in either AASHTO LRFD or the Eurocode.
