Experimental study of the behaviour of reinforced high-strength concrete short corbels

Within the framework of the French National Project BHP 2000 (the BHP 2000 project is detailed in Toutlemonde et dl. [1]), seven high-strength reinfor ced concrete short corbels were tested using concrete from 70 MPa to 120 MP a. The behaviour of a test specimen is characterised by the crack pattern a nd by LVDT and gauges measurements. The results show the influence of the c oncrete strength and that of the reinforcement quantity (Bourget and Delmas [2]). The failure conventional shear stresses computations with the relati ons proposed by B. Foure [3] show that these relations are adapted to the s trength evaluation of the short corbels with a safety coefficient.
