Abstract
to study the effect of cyclic heating and cooling on
the nonlinear analysis of the reinforced concrete plate at different load conditions
before and after cracking up to failure, and it`s effect on cracking and crushing of
concrete and yielding of steel.Also to calculate the stresses and strains due to the
applied load under the effect of cyclic heating and cooling .
The study also present the mathematical mode for the behavior of the
reinforced concrete plate under cyclic heating with different variables , such as
temperatures , duration of heating, and number of cyclic heating ,The relation
between load and deflection .is presented .
Ressiner`s theory has been used to represent the behavior of thick plate . The Finite
Difference method and Dynamic Relaxation have been used in the solution of the
differential equations ..
