Evaluating Fire-Damaged Components of Timber Bridges and Structures
The goal of this research is to adapt a direct test to estimate the residual flexural properties of individual framing members for post-fire evaluations. The adaptation incorporates partial-composite action with an aluminum stock and a cycle of increasing load tests that are applied gradually. The evaluations of the methodology were based on eight, glued-laminated beams of which four were fire-damaged. The fire-damaged specimens were exposed to a time-temperature curve intended to produce a significant zone of damaged wood due to elevated temperatures within the residual wood section. Very good agreements were obtained between the estimated and actual apparent modulus of elasticity and modulus of rupture. The proposed test applies when flexural properties are to be refined beyond estimates that rely solely on reductions in cross section and tabulated values for fire damaged members and members that can otherwise be expected to remain in service.
