Design Study of a Flexible-Membrane Tsunami Barrier Concept

The inundation height of the Tohoku tsunami of 2011 exceeded the design levels of many coastal barriers and several structures collapsed. Hundreds of seawalls and breakers are (planned to be) (re)built in the Tohoku district. There is much debate about the conventional tsunami walls and it is therefore suggested to consider alternative tsunami...

Pipe uplift in liquefied sands: The case of induced earthquakes in the Groningen area

This study considers pipe uplift in liquefied sands in case full liquefaction occurs in the Groningen area. Due to the short vibration time, approximately 2 seconds, uplift is considered in fully liquefied sands without vibrations. The liquefaction time and resistance against uplift are determined by experiments. The resistance against uplift is...

The Design of Inflatable Hydraulic Structures

Additional thesis with a size of 10 European Credits. A Finite Element Method model is established for an inflatable barrier. The inflatable storm barrier of Ramspol in the Netherlands is taken as reference project. The FEM program that is used is called EASY and is specialized in highly deformable structures. With the model, an optimal design...

Project Cartagena: Tunneling the bay

Cartagena is one of the main touristic attractions of Colombia with its good conserved colonial city centre. The city also has an important contribution to the economic growth of Colombia, because of its big port and its beneficial location towards the Panama Channel. However, Cartagena is suffering from problems with the accessibility of...

Het reologische gedrag van de aluminiumgietlegering AA356 in de half-vaste half-vloeibare toestand met en zonder SiC toevoeging

Het pseudo-plastische en thixotrope, tijdsafhankelijke gedrag van de aluminiumgietlegering AA356 in de half-vaste half-vloeibare toestand met en zonder SiC toevoeging is onderzocht met behulp van een rotoviscosimeter. Een geroerde metaallegering in de half-vaste half-vloeibare toestand bestaat uit globulaire primaire vaste fase deeltjes in een...
