Long Span Buoyancy Bridge with Submerged Cable Anchoring

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...

Numerical Simulations of Full Scale Tests Investigating Effect of Fault Movement on Buried Pipeline

This master thesis investigates the response of buried pipelines under ground-induced deformations through the finite element simulations of a testing program undertaken at TU Delft Stevinlab II as part of the GIPIPE research project.

Structural behavior of pressure locked gratings

Pressure locked gratings have many uses, both on land and at sea. This is mainly due to the high degree of flexibility in dimensions and load bearing capacity. Despite the many uses in our surroundings, the term pressure locked grating is unknown to many. This term refers to the way in which the most important connection in pressure locked...

The influence of thermal gradients in steel columns due to pool fires

During this thesis the fire safety engineering approach has been used to investigate the influence of hydrocarbon pool fires on steel columns. Using a fire curve which closely resembles a natural fire curve the temperatures occurring in the steel have been investigated using a Computational Fluid Dynamics (CFD) model. The model consists of the...

Structural Adhesive Bonded Steel-to-Steel Connections: An Introduction for Structural Engineering

Today, there are only a few types of structural engineering applications where structural adhesives play a role, in contrast to other engineering sectors. The possibilities and difficulties of structural adhesive bonding in structural engineering, especially for steel-to-steel connections, are investigated. Practically all structural adhesives...

Effect of TIG-dressing on fatigue strength and weld toe geometry of butt welded connections in high strength steel

When high strength steels are applicated in dynamically loaded structures, fatigue problems can arise. In most current design codes, the fatigue strength of high strength steels is either not discussed or determined as similar to mild steels. This assumption can be related to the dominance of the crack propagation life during in the total...
