Evaluation
of Stress-Laminated Wood
T-Beam and Box-Beam Bridge
Superstructures
Project Overview
Early testing and modeling
of stress-laminated T-beam and Box-beam timber bridge superstructures indicated
that bridges built using this technology appeared to have promising structural
behavior. However, during further field testing, questions arose
about the performance and cost of the bridge systems. This project
assembled a literature review on research and performance studies for stress-laminated
T-beam and Box-beam bridges constructed in the US and abroad. In
addition, completed experimental research results and proposed AASHTO design
procedures were evaluated by comparing their predictions to results from
a finite element model. Field performance of T-beam and Box-beam
bridges was evaluated during an intensive field inspection program for
selected bridges in West Virginia. Bridge costs were also examined
and compared with other traditional forms of timber bridge superstructures.
The final report is still
under review. However, the following links will bring up portions
of the draft final report :
