LOAD TRANSFER FROM HIGH STRENGTH CONCRETE COLUMNS THROUGH ORDINARY STRENGTH CONCRETE SLABS
This paper describes the results of tests of nine reinforced concrete column- slab specimens, in which the columns are of very strong concrete having about 10 k/sq in. compressive strength. While the intervening floor slabs are much weaker. The slab concretes range from about 3 - 6 k/sq in. compressive strength. In addition to the variation in the concrete strength, two different slab thicknesses are included. The interest in this series of tests is axial load transmission through the weaker slab concrete, and no moments are imposed on the slab-column connection. The data along with previously available data are analysed with three objectives. Firstly, to investigate the general adequacy of section 10.15 of the 1995 ACI code ( AC/ 318 - 95 ). The provisions do not appear to be conservation when the column concrete is extremely strong. Secondly, to develop a better understanding of the problem, and to develop a better prediction method or procedure. The third objective is to find out the appropriate parameters for the estimation of the apparent strength of the floor concrete to be used in calculation of the load carrying capacity of columns.
