This paper describes an experimental investigation into the short-term and long-term behaviors of two types of T-shaped lintels made of fiber-glass reinforced plastic with polyester or vinylester binder. Tests were performed at ambient condition and an elevated temperature of 130°F. Results of the tests indicate that the polyester lintels carried less load than similar vinylester lintels. Also, polyester lintels experienced 30% to 40% loss of strength when they were exposed to the elevated temperature. Vinylester lintels lost only 20%. In general, polyester lintels had shorter creep life and larger creep deflection than the vinylester lintels.
