Push-out behaviour of demountable injected vs. blind-bolted connectors in FRP decks

The main challenge for realizing competitive hybrid steel-FRP structures, such as bridges, carparks, is to make the steel and FRP components work together. In this study shear resistance, stiffness and ductility of three types of demountable bolted shear connectors are examined. Two blind-bolted M20 shear connectors and a novel, injected...

Steel weight reduction in offshore wind jacket structures by wrapped FRP joints

This report investigates the potential reduction of steel weight for offshore wind turbine supporting jacket structures, if conventional welded joints are replaced by innovative wrapped FRP joints. This new type of connection is under development by Dr. Marko Pavlovic at the Delft University of Technology, and shows outstanding fatigue...

Bonded FRP/steel deck-to-girder connections: Renovation of movable bridges

Many movable bridges, built in the 1950’s and 1960’s, reach their end of service life or do not meet future traffic demands. Renovation of those bridge, if possible, is preferred over newly built from an economical point of view. Fibre-reinforced polymer (FRP) decks prove to be excellent for retrofitting bridge decks compared to traditional...

A Feasibility Study on Weight Saving in Bascule Bridge Design by Implementing an FRP-deck: A case study on the Amalia bridge

This master thesis contains a study on the implementation of Fibre Reinforced Polymers (FRP) onto a steel bascule bridge, with the aim of weight reduction. As a case study, the Amalia bridge near Waddinxveen (crossing the Gouwe channel) is used. Two alternative design propositions are presented. The thesis has been subdivided into several parts,...

Potential Use of Fibre-Steel Laminates in Hybrid Deck Systems

Over the last two decades Fibre-Reinforced Polymer (FRP) constructions have infiltrated the infrastructure market, particularly in the Netherlands. This is due to the increased number of short-span pedestrian and cycle bridges which are used to traverse canals and waterways. FRP bridges are desirable as they are light-weight, require low...

Feasibility study on fiber reinforced polymer cylindrical truss bridges for heavy traffic

Considering the recent increase in the use of fiber reinforced polymers in the civil engineering industry in general and in the bridge engineering industry in particular, as well as the recently more and more applied cylindrical truss bridge type, this research focuses on the question whether it is possible to combine fiber reinforced polymers...
