Abstract: This study assesses the suitability of four sectional shear methods for predicting the shearcapacity of reinforced concrete members which do not comply with S6-06 Section 14 stirrupspacing and area requirements. The results of the evaluations indicate that the sectional shearprovisions in S6-06, AASHTO LRFD-05 and software Response 2000 appropriately account forvariations in stirrup spacing and area detailing, and present with good agreement betweenpredicted and tested shear capacities for member with deficient shear reinforcement. However,shear capacities calculated using ACI 318-08 do not agree well with tested capacities formembers with less than minimum stirrups. Two modified shear methods are proposed, whichrevise the diagonal crack spacing and concrete contribution area assumed by S6-06. Themodified shear methods improve predictions of shear capacity relative to predictions calculatedusing S6-06 and eliminate the issue of non-convergent shear capacity predictions which can resultfrom evaluation using S6-06.
