Abstract |
In this study, concrete composite beams were tested under two-point loading to evaluate horizontal shear strength. The test variables were a type of composite members (PC+RC, PSC+RC, SFRC+RC), area ratio of high-strength (60MPa) to low-strength concrete (24 MPa), and transverse reinforcement ratio. The test results showed that the contribution of transverse reinforcements and interface conditions had influence on horizontal shear strength. Existing and previous test results were classified according to test methods and the interface conditions and were compared with the predictions of current design codes. On the basis of test results, an improved design method was proposed.
