Abstract:Tests of concentrically loaded slab-column specimens containing either lightweight or normal weight aggregate concrete and shearhead reinforcement made from structural shapes are briefly described. Based on the results of tests on these 21 specimens, a design procedure for shearheads at interior supports is proposed and a design example is presented. Strengths implied by this design procedure are compared with measured loads from tests described here and also with loads from other tests. The proposed design procedure is shown to provide shear capacity in the slab that is consistent with load factors and strength reduction factors being considered for use in the 1970 ACI Building Code.
