A previously established theoretical equation correlating the flexural ductility of a reinforced concrete beam section to the steel ratios and the concrete strength has been extended to account for the effects of the tension and compression steel yield strengths by means of a parametric study. Through...
Production and properties of thermomechanically rolled high strength steel plates with minimum yield strengths up to 700 MPa The principles of thermomechanical controlled rolling, including accelerated cooling, of high strength plates are briefly surveyed in the light of the meta...
