Abstract:

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.
