DESIGN OF REINFORCEMENT TO CONTROL CRACKING DUE TO IMPOSED STRAINS

The amount of reinforcement to control cracking of concrete structures is investigated. The effect of non-uniform cooling and shrinkage is studied with regard to the external and internal restraint acting on the structure. By means of a simple model several different cooling processes and restraint degrees are simulated for different wall sections. The results of the computation give the force actually arising in the structure during the cooling or shrinkage process and the range of softening and cracking in the concrete section. The aim is to investigate the parameters having major impact on the magnitude of this force and consequently influence the design of minimum reinforcement. The investigation concludes some simple guidelines regarding the design of minimum reinforced concrete structures in practical cases. (A) For the covering abstract see IRRD E101472.
