Experimental study of the post tensioned prestressed concrete corbels

The results of experimental investigation of 6 symmetrical double prestressed corbels of variable shear span to depth ratio and variable location of prestressing bars are presented in the paper. The post ten- sioned corbels were prestressed with Macalloy 1030 bars of 25 mm in diameter. The results of the tests were compared with the cracking and load carrying capacity of corbels reinforced with passive reinforce- ment. As a result of the analysis, a formula of calculation of force causing the inclined crack in the central area of the corbel was proposed. Usability of the selected computational schemes applying the truss mod- els, as well as the shear–friction hypotheses, were assessed
