Flexural Strength of Reinforced Concrete Slabs with Externally Applied In-Plane Force; and Strength of Slabs Subjected to Multiaxial Bending and Compression.

Abstract

This report describes an investigation into the behavior of reinforced concrete floor slabs which are subjected to compression forces in the plane of the slab as well as to transverse bending moments. The first report describes tests of a series of 6-ft sq. slabs representative of typical interior panels of beam-supported slab floors. The slabs were subjected to known in-plane compression forces and then loaded to failure under transverse loads. An approximate analysis is developed which leads to a conservative prediction of the strength of such structures, and which gives a reasonable prediction of the load-deflection relationship and consequently of the energy absorbing capacity of the system. The second part of the report describes tests on six slabs in which the reinforced concrete section was subjected to a uniform moment and compression field in all directions. The tests confirmed that the response of the slabs under such multiaxial bending and compression could be satisfactorily predicted using the same principles and techniques that are routinely applied to members subjected to uniaxial compression plus bending, as is the case for columns.
