Design and optimisation of a structurally separated roof structure for event venues

Nowadays football stadium encounter a lot of problems. Often services are outdated and the capacity is often too large or too small. These capacity problems especially occur in stadium that are built for major tournaments. When the tournament is finished, no appropriate tenants can be found and the stadium often remains empty. Another problem...

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...

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...

Optimising the Design of a Steel Substructure for Offshore Wind Turbines in Deeper Waters

In the need for more green energy a prominent role is reserved for wind energy. Offshore wind energy in deeper waters capitalises on more efficient wind properties and increased public acceptance compared to onshore wind energy and wind farms close to shore. In the coming years the offshore wind market is expected to evolve rapidly, especially...
