Improving the quality control of Cofra Roller Compaction: A study on the relation between the impact acceleration and the soil compaction

Ground improvement in the form of soil compaction plays a important part in reclamation projects. The development of the Cofra Roller Compaction (CRC), a non-circular impact roller, has proven to be valuable in these projects. However, the heterogeneity of the subsoil causes locally a non-uniform degree of compaction. Traditional compaction...

The dynamic behaviour of hydraulic structures caused by wave impact loads: Enhancing the present design method in time and space

At this moment hydraulic structures are designed based on a simple method: the Dynamic Amplification Factor (DAF) method. This method does not consider the full dynamic interaction between the wave impacts, structure and water. The research project DynaHicS focusses on the dynamic behaviour of hydraulic structures, taking into account fluid...

An Investigation into Solution Strategies for Nonlinear Finite Element Analysis of a Concrete Column under Blast Loading

An explosion event, having a low probability of occurrence but severe consequences, due to a possible structural collapse, is a so-called "Low Probability and High Consequences (LP-HC)" event[13]. Due to the severe consequences, blast puts a great threat to public security. Thus, civil engineers should take these extreme cases into consideration...

Structure-soil interaction for horizontally polarised shear waves: Formulating SH-waves in a homogeneous elastic continuum with generalised boundary conditions

When modelling a structure-soil system, interaction stresses at the interface of the structure and the surface of soil layer influence the dynamic behaviour of the system. These interaction stresses are not accounted for in many simplified models that evaluate the behaviour of the soil layer and the structure separately. Modelling a fully...

The Hybrid Monopile: Design of a novel foundation structure for large offshore wind turbines in intermediate water depths

In the 26 years since the first offshore wind farm was installed in Vindeby, Denmark, the offshore wind industry has undergone remarkable growth. Recently, this growth has accelerated, advancing farms rapidly into deeper water and utilizing larger turbines. As offshore wind farm developers continue to look towards heavier, higher capacity...
