Abstract
Background: Deferent types of reinforced concrete beams wrapped with GFRP pultruded profiles and a control RC beam are tested under three points loading. Objective: The moment-curvature curves of all tested beams are obtained based on the experimental study. The change characteristics of flexural stiffness for tested beams are analyzed, and the short-term flexural stiffness formula is derived. Results: Finally the computed values of midspan deflection for tested beams are achieved.
