Autogenous Shrinkage of Cementitious materials containing BFS

In the Netherlands blast furnace slag (BFS) cement is commonly used. Concretes with this type of cement are known for good durability properties. Where concrete is designed to crack in order to let the incorporated steel reinforcement take over tensile stresses, it is mainly for durability reasons that non-designed cracking of concrete is...

Double curved precast load bearing concrete elements

The construction of free form building stagnated, due to the high construction cost of it. Double curved surfaces are only applied at projects with a high profile and projects above average budget during years. The problem with double curved surfaces is mainly the formwork. The present days used techniques to construct these formworks are...

Stroming van beton in diepwanden

During the construction of a station of the north south line in Amsterdam a leak in the diaphragm wall lead to severe damage to adjacent buildings. The leak consisted of a clay deposit caught near the joint. Until the excavation reached the level of the deposit, the deposit acted as a seal. After the excavation it started to leak and eventually...

Comparison of quay wall designs in concrete, steel, wood and composites with regard to the CO2-emission and the Life Cycle Analysis

This thesis focuses on quay wall structures in the Port of Rotterdam. A quay wall is a soil retaining structure where ships can moore and transfer goods. Over the centuries the developments in quay wall structures have been tremendous, due to increasing ship dimensions, loads and crane designs. Next to that climate change is a hot topic nowadays...

The elevated metro structure in concrete, UHPC and composite

In some large cities, the infrastructure is elevated high above the ground. An elevated metro system has the advantage that its construction is cheaper compared to an underground metro system. The construction time is relative limited and the physical barrier is small. The large elevation has a positive influence on the visual hindrance of an...

Simulation of steel-concrete bond-slip with sequentially linear analysis using interface elements

Concrete armour units for breakwaters: A study on the structural integrity

One of the most basic types of breakwaters is the rubble mound breakwater which in essence is a heap of stones consisting of a core of fine material covered by an armour layer of big rock or concrete elements. Mostly unreinforced, these concrete elements exist in different sizes and geometries varying from massive concrete cubes to more...

A numerical analysis of pull-out anchor bolts

Anchor bolts are often used in concrete or steel structures. Nevertheless still empirical design procedures are used in order to determine the dimensions of the structure. Non linear fracture mechanics tries to describe fracture of heterogeneous materials like concrete. In the classical representation of concrete fracturing (figure 1.1),...
