Reports of seismic effects on reinforced concrete bridges, especially those built according to the codes of practice of the seventies, show that a lot of them behave poor [...]

An experimental cyclic campaign of RC hollow piers has being carried out in the Laboratory for Earthquake and Structural Engineering (LESE) of the Faculty of Engineering [...]

This paper presents two main parts, encompassing the experimental assessment and the numerical modelling of vibrations induced by railway traffic. Firstly, a global descr [...]

Non-linear reinforced concrete bridge piers’ cyclic behavior is known for being influenced by shear. That is particularly visible in the case of hollow piers where the [...]

The main objectives of the paper are to evaluate the relevance of the non-linear soil behavior on the track response and to validate the proposed methodology which includ [...]

The strong motivation for this work relies on the peculiar structural behavior of RC hollow section piers, quite similar to structural wall, and therefore the higher diff [...]
