In recent years, Wire and Arc Additive Manufacturing (WAAM), is gaining attractions both from academia and industry, because it has the potential to substitute or complement the traditional manufacturing methods. Traditional materials and methods are reaching their limitation when demanding and special applications are considered.

Orthotropic Steel Decks (OSDs) are widely used in various types of steel bridges due to their benefits of light weight, high load bearing capacity and speedy construction. Although many improvements in aspects of design, fabrication, inspection, and maintenance have been achieved over the years for such bridge decks, fatigue remains a...

Fatigue is an important issue for orthotropic steel deck (OSD) bridges and therefore a design criterium. Cracks will initiate at several locations of the bridge deck. It is likely that a crack at the trough web to deck plate joint at the crossbeam will initiate first. This crack initiates at the weld root and propagates through the deck plate. A...

In the past decades, great progress has been made in analyzing lateral torsional buckling of slender beams. The phenomena has been accurately described by differential equations, closed form solutions are available for specific cases and the solution for any load and any boundary condition can be obtained by finite element analysis. Timber and...

A parametric study, using the FEM-software package ABAQUS, validated on experimental results found by Abspoel, was conducted on S690 steel plate girders to address if the results of the previous researches was valid. Using a slightly different analytical model the results show the maximum web slenderness of this steel grade in both 6000 mm2 and...

The re-use of building components and structural elements is an underdeveloped practice which could be an important strategy in the global paradigm shift towards a circular economy. Steel is one of the most important structural building materials which combines incredible strength, favourable mechanical properties and excellent durability...

The interest in high strength steel (HSS) shows an increasing trend mainly due to its high yield strength, low weight to strength ratio, decreasing costs of the base material and fabrication. The proposed 2020 version of the Eurocode 3 part 1-8, still under discussion at the time of writing of this thesis, covers steel with yield strength up to...

The focus of this research was the implementation of a permanent steel fibre reinforced underwater concrete floor (SFRUCF) as a permanent structural floor. A model was created that can describe the soil structure interaction of an SFRUCF including the highly non-linear behaviour of SFRC. The soil structure interaction of the UCF was modelled in...

The building and construction sector play a key role in achieving a sustainable development. In European countries, buildings are responsible for 40-45% of energy consumption, leading to significant amounts of CO2 emissions. The implementation of reusable structures lead to less waste and harmful emissions to the environment. The main purpose of...

Conversion coatings are generally required to enhance organic coating adhesion and corrosion resistance on galvanized steel. Until a few decades ago, chromate conversion coatings were the most common conversion coatings in the industry owing to their exceptional performance in this regard. However, the adverse effects associated with hexavalent...

Orthotropic steel decks are widely used in bridge construction nowadays, especially in case of long span bridges. One of the main problems of bridges that utilize this technology is the susceptibility to fatigue failure. Cyclic loading due to wheel loads, in combination with the complex network of welded details, make such types of decks prone...

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...

The building industry is fragmented. In the case of steel structures, two parties are involved in the design. The engineering firm designs the structure, and at a later phase the steel contractor designs all the detailing. This fragmentation restrict the possibilities of creating a cost optimal design. Currently, engineers often optimise on...

More than 50 locks owned by Rijkswaterstaat need replacement or renovation in the coming 40 years. Due to this fact an opportunity for changing the traditional way of building and maintaining navigational locks has arisen. Because of the replacement/renovation of locks in the coming time, implementing a new owning and building strategy is...

A composite slab consisting of in-situ casted reinforced concrete on profiled sheeting, which is connected to steel beams by shear connectors, is a common structural flooring system in office and multi-storey car park buildings. The headed welded studs, which are most widely used shear connectors, are inexpensive and easy to install because they...

Sustainability concerns steer the construction sector towards adopting a circular economy philosophy. Steel-concrete composite beams are extensively used in multi-story buildings and bridges due to their competitive construction and efficient material use. Currently the composite action is mainly achieved by headed shear connectors welded to the...

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,...

Wire rope slings are commonly used lifting tools in all sorts of engineering applications. Usually, slings are either loaded axially or they are bent around a load bearing element such as a shackle or pipe. In the latter case, the combination of bending and axial loading introduces additional stresses within the wire rope that cause a...

Hot-dip galvanizing is a well-known process to increase the corrosion resistance of steel. As a by-product dross is formed in the Zn-bath. The dross particles are composed of Fe, Al and Zn in the form of Fe2Al5Znx and interact with the hardware that is submerged in the Zn-bath and eventually accumulate on the surface of the hardware. This...

This research studies the experimental and numerical behaviour of a simple beam to column joint using a fin-plate welded to an rectangular hollow core section. The following aspects of the joint are investigated:
The resistance of the welded connection.
Defining the force distribution inside the joint.
Improvement of the design...
