Reinforced Concrete Beam-Column Connections and BS 8110

The influence of compressive axial load on the shear capacity of reinforced concrete elements is investigated, using results from tests on 15 external reinforced concrete beam-column connection specimens. Shear stresses in the connection zones of these specimens are compared with values predicted by the design equations in BS 8110 and observations made concerning the applicability of these equations. The revised eqns. (6a) and (6b) in BS 8110 are presented and recommendations made for assessing shear stresses at initial joint cracking and specimen failure. Bearing stresses within bends in the reinforcement in the connection zones are also evaluated and compared with the recommendations of BS 811O.
