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 standard sign gantries at the highways in the Netherlands have different geometrical and structural characteristics than sign gantries in other countries. The sign gantries have in total four oblique columns instead of two straight columns and have a triangular shaped spatial truss beam. The design loads that are currently taken into account...

For the E39 highway in Norway a project is underway to replace the ferry crossing in the Sognefjord with a fixed crossing. Previous thesis projects have resulted in a design for a 4500 m long buoyancy bridge which consists of 22 concrete pontoons that carry a steel truss superstructure. To reduce lateral movements the pontoons are fixed to a...

The horizontal shear capacity of steel-concrete composite floors can only be determinedwith full scale experiments since no good theoretical model is available. Since the properties of the sheeting can change over time due to wear of the rollers, regular testing of the steel concrete slabs is therefore necessary. The last research on the ComFlor...

Offshore wind power provides an alternative to fossil fuels while negating the effect of visual and auditive distortion of onshore wind turbines. Located several kilometres offshore, the transmission cable resistance becomes substantial. To limit the losses, the voltage in the cables is increased in a substation. As this structure is often the...

In this thesis research has been performed to the strength and fatigue behaviour of existing riveted steel structures. The objective of this study is to research the ways of making a structural model that accurately predicts the behaviour of a riveted detail. For this purpose, a critically stressed riveted node from the steel road bridge the...

In the last few decades great progression has been made in the research and development of a fairly new type of concrete called ultra-high performance concrete (UHPC). This high-tech material has excellent material properties compared to conventional concrete and has the potential to make more slender and lighter structures. However the material...

The United States of America – and more specific the state of Illinois – are dealing with a problem of Asian carps spreading from inward waterways to the Great Lakes. The Asian carp was originally brought to America to be used in study?s on agricultural pounds, but escaped after series of flooding. The Asian carp has no natural enemies in the...

The high levels of wind and wave loads on offshore structures make fatigue analysis a significant parameter that has to be taken into consideration throughout an offshore structure design. Steel tubular members are widely used in offshore (wind) industry due to their efficient structural behaviour. The welded connections between the different...

Many old moveable bridges have exceeded their technical lifetime. Replacement of the foundations is expensive and often unnecessary if the new bridge superstructure is lighter than the old one. With stricter design guidelines being in effect nowadays, a conventional orthotropic steel deck design will end up being heavier. A lightweight fiber...

Wire rope is used in numerous applications such as elevators, power lines, suspension bridges, ships and the mooring of offshore structures. In many of these applications wire rope needs to be bent. Currently the Norwegian certification instance Det Norske Veritas (DNV) prescribes a capacity reduction factor for bending wire rope. It is unclear...

This study investigates the factors that support or obstruct the use of steel grade S460 in the Dutch building industry. The research was limited to European hot-rolled sections and focused on buildings which have primarily a non-residential function. In order to identify these factors, a qualitative (exploratory) research study has been carried...

In the Netherlands buildings are designed using a grid with multiples of 3.6 meter. Within these designs floor spans of 7.2 meter are popular (double grid size). The deep decks of composite floors at this moment in time are designed to reach an unpropped span of 5.5 meter. This master research is focused on finding a possible deck design for a...

The graduation thesis focuses on providing insight in the consequences of subsiding ground on soil anchors. With the years, the bars of an anchored sheet pile walls for example, can be unfavourably loaded due to subsiding soil. As a result of these lateral loads, the bar will deform and elongate, causing the stresses to increase. The...

The purpose of this MSc thesis is to find a feasible concept for a circa 4500 m long buoyancy bridge, which is located at the Sognefjord in Norway. The concept should be structurally and aesthetically competitive. In contrast to bridges on shore with fixed supports, a buoyancy bridge is supported on floating pontoons. As result, loads will cause...

A number of load modes and comfort design guidelines, with the purpose of analyzing the comfort level of target structure, has been introduced in the last few years. The approaches to these issues have in many cases been very different in both how much in detail it goes when describing the pedestrian load and to what extent the load case has to...

The current calculation methods which determine the capacity of pinned connections provide different results. In this thesis a detailed look on those theories and the effect of different parameters is studied. Because it is hard to provide any conclusions about just comparing these theories also a FEM analysis is done. In this thesis the FEM...

Dynamics of railway bridges is a complicated problem that normally needs nu- merical simulation to conduct researches on. However, this thesis takes advan- tage of the numerical results provided in previous researches and based on these researches, further conclusions are made by using them in simplified model. Recently long span railway bridges...
