Abstract:
This work presents a study of the structural behavior of segmental concrete beams with external prestressing, focusing on the response of these structures under shear. Six tests have been performed on beams to evaluate their shear response and load-carrying capacity at different levels of prestressing. To obtain design guidelines about reinforcement detailing in such structures, the structural response under combined flexure and shear has been carefully inspected. Moreover, to evaluate the possible benefits that the use of steel fiber-reinforced concrete (SFRC) could carry, tests were conducted on both conventional and SFRC elements.
