Title: Sheer Strength of Reinforced Structural Lightweight Aggregate Concrete Slabs
Author(s): Eivind Hognestad, Richard C. Elstner and J. A. Hanson
Publication: Journal Proceedings
Appears on pages(s): 643-656
Abstract:To aid development of the 1963 ACI Building Code, sixlightweight concrete slabs were tested to explore the shear strength of slabs made with structural lightweight aggregate concrete as compared to similar slabs made with normal weight concrete. This limited investigation indicated that the shear strength of lightweight slabs is characterized by the splitting tensile strength of the concrete rather than by compressive strength. This conclusion is reinforced by previous findings regarding the shear strength of lightweight beams. The derivation of the 1963 ACI Code provisions fo the shear strength of lightweight aggregate concrete slabs is explained and substantiated by the test findings.
