De nieuwe generatie Maasstuwen: Een geschikte uitvoeringsoplossing voor een nieuwe stuw bij Linne

The weirs in the river Meuse reach their theoretical lifespan. The weirs were built in the early 1930s and now one is faced with a replacement task. Various studies have been carried out in recent years on the future of the weirs in the river Meuse. This concerns research into the entire weir system, different types of weirs and the way in which...

Transverse Shear Capacity of Deep Composite Slabs: Based on a Finite Element Analysis of ComFlor 210

For calculation of the resistance of a composite slab against the transverse shear force, the Eurocode 4 (composite structures) simply refers to the calculation procedures of the Eurocode 2 (concrete structures). It is assumed that the composite slab consists out of a consecutive range of concrete ribs in its width direction, which are solely...

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...

Ship collision on temporary structures: Combi-walls under collision loading

When designing a construction pit adjacent to a navigation channel, the event of a ship colliding with the structure is something to take into account in the design of the pit. However, several aspects regarding ship collisions, i.e. the probability of occurrence of a collision, the magnitude of the collision force and the influence on the...

Assessment of steel-concrete shear connector system with resin injected bolts

The building and construction sector play a key role in achieving a sustainable development. In European countries, buildings are responsible for 40-45% of energy consumption, leading to significant amounts of CO2 emissions. The implementation of reusable structures lead to less waste and harmful emissions to the environment. The main purpose of...

The behavior of composite deep deck ComFlor210 under concentrated load

The research concentrated on a behavior of the deep composite deck ComFlor210 under a concentrated force. The distribution of a concentrated force in ComFlor210 was studied numerically and analytically. <br/>The finite element model of a composite slab with 5.4m span showed good agreement with test results in the elastic stage. The parametric...

Towards a demountable composite slab floor system

A composite slab consisting of in-situ casted reinforced concrete on profiled sheeting, which is connected to steel beams by shear connectors, is a common structural flooring system in office and multi-storey car park buildings. The headed welded studs, which are most widely used shear connectors, are inexpensive and easy to install because they...

Analysis of the response of temporary overhead sign structures subjected to overheight vehicle impact

Overheight vehicle impact is the impact of a heavy dump truck with a rigid raised trailer on the beam of a light-weighted and flexible temporary overhead sign structure. The structure is initially not designed to resist overheight vehicle impacts and the impacts occurring during construction works with impact velocities up to 40 km/h result in...
