Strength and behaviour of corner and edge column-slab connections in reinforced concrete flat plates
Abstract
The object of this investigation was to study experimentally
the strength and behaviour of the corner and edge column-slab connections
in reinforced concrete flat plates under different loading conditions.
The view was to obtain data useful for establishing a method for
analysis of these connections.
Two test programmes involving tests on nineteen full size connections
were conducted to study their strength and behaviour under load.
The main variables included were: concrete strength, ratio of column width
to the effective depth of the slab, the reinforcement ratio, ratio of
bending moment to axial shear and condition of loading i.e. monotonic or
reversed.
A theoretical method for the analysis of a corner or an edge
connection subjected to the effect of bending moment or combined axial
load and bending moment was developed which takes into account the effects
of the above mentioned variables. The method checked successfully against
the test results of the writer and those of other investigators in the
following cases.
1. Corner connection subjected to uni-axial bending moment about one
major axis of the column cross section only.
2. Corner connection subjected to symmetrical bi-axial bending moment .
3. Edge connection subjected to bending moment in a plane perpendicular
to the free edge of the slab.
4. Corner connection subjected to combined axial load and symmetrical
bi-axial bending moment.
5. Corner connection subjected to combined axial load and bending
moment about one major axis of the column cross section only.
6. Edge connection subjected to combined axial load and bending
moment in a plane perpendicular to the free edge of the slab
only.
