Reinforced Concrete Corbels Shear Test: The Triangular-Truss Method Evaluation

In this paper, five reinforced concrete double-corbel specimens with the same designed bearing capacity are produced according to triangular-truss method (TTM) in GB 50010-2010. Corbels different dimensions and reinforcement configurations obtained by separately varying compressive strength shear span. The differences mechanical performance load-bearing of corbels compared evaluate accuracy rationality TTM under specific variables. Then, predicting 50010-2010, ACI 318-19, EC 2, CSA A23.3-04, softened strut-and-tie method, Russo is compared. results show that safety factor (ratio actual capacity) increased from 1.419 1.718 when improved 20.8 MPa 65.3 MPa; 1.414 1.859 span–depth ratio 0.25 0.67. Compared predictions A23.3-04 for closer test values. level codes 2 essentially same; both SSTM STM accurate predictions.
