Performance in Transverse Direction of Fiber‐Reinforced Polymer Bridge Decks

Thomas Keller, Julia De Castro San Roman Fest, Sonia Yanes Armas

Pultruded glass fiber‐reinforced polymer (GFRP) bridge decks distribute punctual vehicular loads to the underlying superstructure and can also act as the upper chord of hybrid main girders. The deck’s structural performance in both cases is influenced by i ...

Experimental investigation on seismic behaviour of slab-column connections

Katrin Beyer, Aurelio Muttoni, Ioannis Sokratis Drakatos

Code design of slab-column connections to resist seismically induced drifts is currently based on empirical relationships for both moment and deformation capacity. The results of tests on slabcolumn connections are however sensitive to the conception of th ...
