خلاصه مقاله:
Beam column joint (BCJ) specimens tested under monotonic loading were compared with joint shear failure predicted according to EC8-NA [1] and ACI352 [2]. Inadequacy of these design codes for accurate estimations of the shear stresses at BCJ are identified. A design rule for the prediction of BCJ failure for high strength concrete (HSC) is given. The proposed method offer better accuracy when the results are compared with design rules from the above codes and research results. Finite element numerical models for BCJ specimens were compared with the experimental ones. Furthermore parametric investigations of the influence of Central Vertical Bar, CVB, on the shear capacity of HSC- BCJ were conducted. Strut and tie model for BCJ with CVB was developed to guide the designers towards using the proposed design rule to calculate the amount of shear CVB and stirrups required in order to resist the excessive joint shear.
