Abstract: High Strength Reinforced Concrete made of high strength concrete and high yield limit steel reinforcement (B 90 FeE 800),has already been investigated mainly concerning tensioned ties and beams submitted to bending and shear.
Slabs were still to be considered.
The present paper deals with this subject,considered from the serviceability point of view.
The experimental method,inspired by former tests carried out on usual reinforced concrete plates in our own laboratories,is shortly described in the first section.
The results of the tests,local deformation of concrete and of steel rebars,global deflexion of the slab,are given in the second section,in the form of graphs of their variations with the loading transverse pressure.
The third and last section is dedicated to the anal sis of all the results that have been collected.
Reversibility and crack initiation steps have given particular care.
The most unexpected conclusion has been to display the contribution of the reinforcement steel yield limit increase to the different load levels corresponding to the different marks which stake out the behaviour of reinforced concrete slabs within the small deformation range.
