دراسة توزيع أجهاد الترابط بين الخرسانة و فولاذ التسليح بإستخدام طريقة العناصر المحددة

الملخص EN

In this investigation, the bond stresses between the reinforcement and concrete was studied through using non-material interface elements which are able to produce the bond stresses for the reinforced concrete beam gradually loaded from zero till failure.

Depending on ( Jawad ) program which is a non-linear analysis program of plain and reinforced concrete beam through discrete-crack approach by using finite element method.

The stiffness matrix derivation of interface element and the way of non-linear treatment was explained.

The distribution of bond stresses drawings along the steel reinforcement for different values of loading were achieved before and after cracking.
