shipped to the bridge site. This system requires a closure
strip to be placed on-site between the precast concrete girders
to make it continuous for live load distribution. Shah et
al. developed and tested to collapse a number of connection
details between the flanges of the precast concrete deck
bulb-tee girders. In continuation of these efforts to accelerate
the construction of new bridges and the replacement of
deteriorated bridges, a precast concrete barrier wall system
was developed and tested to collapse.3
This paper presents
a summary of the structural details of the proposed precast
concrete barrier system, fabrication process, and results of
static load tests to collapse on five barrier configurations.
A comprehensive literature review of previous work on
barrier wall joints and barrier-to-deck joints is presented
elsewhere.3
