Influence of Ductility in the Design of (High Strength) Steel Bridges

In connections of steel structures stress concentrations occur due to the rapid geometric changes in the cross section. If the material has sufficient ductility then, due to plastic deformations, forces are redistributed so there will be equilibrium in the internal forces. In design codes this is accounted for by imposing certain requirements...

Upgrading Old Movable Bridges with FRP Deck Application: The case study of Wilhelminabrug

Fibre Reinforced Polymer bridge decks, thanks to their beneficial properties and various advantages over traditional materials, have great potential as a material used in bridge engineering. They exercise high specific strength and stiffness-to-weight-ratio, a property particularly interesting from the point of view of designers, as it provides...

Innovative design for lock gates - curved sliding gate; case study: IJmuiden Nieuwe Zeesluis

Design of a lock gate for Nieuwe Zeesluis in IJmuiden becomes a challenge when the boundary conditions limit the choice for the conventional types of the gate. The available width of the lock does not allow a straight rolling gate to be considered as a possible alternative as it is in most similar cases. All the initial efforts of this study...

Use of High Strength Steel Grades for Economical Bridge Design

Bridges offer great potential for the use of high strength steel grades (HSS). The main advantages are generally a result of reduced weight and cross-sectional dimensions. Design stresses can be increased and plate thickness may be reduced, resulting in significant weight savings. Reduced plate thickness can also save on welding costs as well as...
