Strengthening and rehabilitation of two damaged bridges in the motorway M-410 in Madrid (Spain)

The new highway M-410 in Madrid was constructed in the year 2007. This motorway near to Parla city crosses the road from Madrid to Toledo. To solve this crossing it was needed to constructed three bridges, the central with two spans over the existing motorway and the other two with one span at each side of the previous one.

Typological/Placement possibilities and limitations of ductile behavior of bridges in seismic areas

Consideraciones sobre la ductilidad en zonas sísmicas. This paper analyses the ductile behavior of a highway overpass located in a seismic zone. The paper presents the results of a pushover analysis that enables the design engineer to estimate the behavior of the bridge’s columns in two directions in an independent manner. The differences with the theoretical bilinear behavior are described and explained. Indications are given on the need and possibilities of taking advantage of ductility in different seismic events scenarios.

Experiments with liquid bridges in simulated microgravity

A feature of stability diagrams of liquid bridges between unequal disks subjected to small axial gravity forces is that, for each separation of disks, there is a value of microgravity for which an absolute minimum volume limit is reached. The dependence of such microgravity values on the liquid bridge geometry has been experimentally checked by using the neutral buoyancy technique, experimental results being in complete agreement with theoretical ones. Analytical background assuring the experimental procedure used is presented, and a second order analytical expression for the equilirium interface is also calculated.

Axisymmetric long liquid bridges in a time-dependent microgravity field

This paper deals with the dynamics of liquid bridges when subjected to an oscillatory microgravity field. The analysis has been performed by using a one-dimensional slice model, already used in liquid bridge problems, which allows to calculate not only the resonance frequencies of a wide range of such fluid configurations but also the dependence of the dynamic response of the liquid bridge on the frequency on the imposed perturbations. Theoretical results are compared with experimental ones obtained aboard Spacelab-Dl, the agreement between theoretical and experimental results being satisfactory
