Sustainable Design Development of a Concrete Lock Chamber: Reaching a Sustainable and Durable Design of a Ship Lock Concrete Hard Structure, Enabling Navigation Through the Haringvliet Storm Surge Barrier as Part of the Delta21 Project

Concrete is the second most used material in the world after water and recent trends show no slowing down of the concrete use around the world. Concrete is also a huge contributor to CO2 emissions as it makes up 8% of emissions. This study investigates the optimization of concrete structures to reduce environmental impact while maintaining...

Design of concrete spheres for energy storage at the ocean bed: An optimisation of the conceptual design

In the energy sector, a transition is made from fossil fuels to sustainable energies. Due to an irregular supply of these sustainable energies, it often occurs that there is a mismatch between supply and demand. Energy storage is a promising technique to overcome this. In this thesis, the aim is to store gravitational energy in concrete spheres...

Validation of Sequentially Linear Analysis for Quasi-Brittle Behaviour of Reinforced Concrete Structures under Proportional and Non-Proportional Loading

The aim of this thesis was to objectively and quantitatively assess the accuracy and robustness of two-dimensional sequentially linear analysis (SLA) in comparison to nonlinear finite element analysis (NLFEA), for a range of experiments of reinforced concrete structures with proportional and non-proportional loading schemes. Non-proportional...

Lattice Modelling of Concrete-Ice Abrasion

An increasing number of activities are moved into Arctic regions. As oil and gas companies are exploring the options in these regions, structures are required which can withstand the severe environmental conditions. Existing structures are subjected to heavy mechanical loads due to moving ice sheets. For concrete structures in particular ice...
