Abstract
The main objective of the paper is to develop a simple
method of predicting the ultimate load for any reinforced
concrete structure in a state of flexure. The method of
predicting the ultimate load for any material viz. reinforced
concrete is considered as an elasto-plastic material obeying
the Wood-Armer yield criteria. The analysis is carried out
using a non-linear elasto-plastic finite element program.
The numerical results were compared to four reinforced
concrete slabs. The results were also compared with the
predictions of another non-linear finite element program
which modelled the slab as consisting of a series of concrete
and steel layers in a state of plane stress. The method was
found to give acceptable results and the computation time
was more economic than that of the layer program. The slab
ultimate loads were predicted and were found, on average, to
be 0.96 of those obtained experimentally.
