Buildings in Barcelona protected from railway-induced vibrations with base isolation [PDF]

, 2014
This work describes two mid-height RC base isolated buildings recently erected in Barcelona. Both buildings are located near the main railway station in Barcelona (Barcelona-Sants), thus undergoing dynamic excitations due to intensive railway traffic ...

Ultrasonic isolation of buried pipes

, 2015
Long-range guided wave testing (GWT) is used routinely for the monitoring and detection of corrosion defects in above ground pipelines. The GWT test range in buried, coated pipelines is greatly reduced compared to above ground configurations due to ...

Shaking Table Tests and Numerical Analysis of Rocking Vault‐Shaped Segmental Piers Equipped With an Annular Double Sliding System

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT To enhance the structural robustness of bridges, a rocking arch‐shaped segmental pier with a double sliding system was previously proposed as a low‐cost solution to protect bridges in developing countries. The rocking behavior is triggered by halting the sliding motion, which increases the horizontal load‐bearing capacity and limits ...

Fluorene‐based blue emitters: On the path to electrically pumped organic lasers

FlexMat, EarlyView.
Electrically pumped efficient operation remains unrealized, a major challenge in optoelectronics. Fluorene‐based blue‐emitting semiconductors are promising gain media, thanks to their structural tunability and favorable emission properties. This review summarizes recent advances, highlights their reliability and versatility in lasing, and outlines key ...
