Title: FINITE-ELEMENT MODELING OF RED MAPLE GLUED-LAMINATED T-BEAMS AND BRIDGE BEHAVIOR

The red maple T-beam stiffness increase was determined for T-beams assembled with and without gaps between deck panels. The T-beam stiffness increase was predicted to within 5% for T-beams assembled with gaps between deck panels and to within 3% for T-beams assembled with no gaps between deck panels. Red maple glulam longitudinal stringer-transverse deck bridge maximum midspan beam deflections were predicted to within 6% for one-lane loading and to within 7% for two-lane loading.
