The goal of developing an appropriate mathematical model for the static behavior of the system was realized through theoretical and experimental studies of reduced-scale double T-beams which modeled glulam bridge cross-sections. Results, to date, have shown that recognition and quantitative evaluation of the composite action in glulam bridges is feasible for full-size bridges. Theoretically composite design can result in up to as much as 50% reduction in deflection as opposed to current design procedures which neglect this component interaction. Design improvements could lead to even greater amounts of increased stiffness as well as increased strength. Suggestions for future research are directed at further quantification of design methods which must include wheel load distributions along with influences of repetitive loading and other variables which typify real bridge loadings.reportsengCopyright and other restrictions may apply.
