Abstract

This work confirms results indicated by previous research that uniformly
distributed loading leads to higher reinforced concrete (RC) beam shear capacitycompared
to 1 or 2 point loading. Different design methods are compared in this
investigation, including those by ACI (1) and other Codes.
Twelve beams, without stirrups, are tested in this work to farther investigate the
influence of distributed loading. Two design equations are proposed in this work, one
includes the size effect and the other without it. The former has proved to be the more
accurate.
Of 200 test results obtained from the literature, the proposed design equations
lead to a COV value of Vtest /VDES of 16.8% and 17.1%. These compare favourably
with other design methods.
