Fire resistance of existing structures: Assessing the fire resistance of existing concrete buildings

Many vacant buildings that are reused are constructed in concrete. With concrete, one thought to have found a solution for the fire resistance of buildings. Today it appears that the fire resistance of concrete is not always a matter of course. Therefore, it is important to properly asses the fire resistance of existing concrete buildings. With...

Assessment of passenger comfort according to Eurocode in Dutch trains travelling over tied-arch railway bridges

With increasing velocities of trains, passenger comfort starts to play a larger role in the design of railway bridges. There is little experience with the Eurocode passenger comfort criterion in the Netherlands. It is relevant for the industry to have a way to fulfil this criterion, also in an early stage of railway bridge design. A sufficiently...

A simplified model for assessing lateral railway bridge resonance behavior

Dynamics of railway bridges is a complicated problem that normally needs nu- merical simulation to conduct researches on. However, this thesis takes advan- tage of the numerical results provided in previous researches and based on these researches, further conclusions are made by using them in simplified model. Recently long span railway bridges...

Vergleich der nationalen Anhänge der EN 1992-1-1 zum Thema Querkraft und Durchstanzen

Der Eurocode 2 (EN 1992-1-1) beschäftigt sich mit der Bemessung und Konstruktion von Stahlbeton- und Spannbetontragwerken. Eine eingehende Betrachtung und der Vergleich der nationalen Anhänge sind notwendig, um die Unterschiede der national festgelegten Berechnungsparameter zu verifizieren. Dieser Aufsatz gibt einen Überblick über die...

Fatigue and shear failure. Differences between NEN and Eurocode.

Within this document the differences arising from the transition of the NEN (Dutch code) to the Eurocode are studied with respect to shear failure and fatigue. These differences are investigated on a global level, where in addition the fib Model Code is taken into account. In the next part the actual differences are determined within a case...

Dwarskracht in zinktunnels

With the introduction of the Eurocode, different formulas are used for shear tests in concrete structures than the previous Dutch standard.These formulas are often used in new building designs. If the result compared with the Dutch standard is either favorable or unfavorable, the design should be modified. It is interesting to research the...
