BEHAVIOUR AND SHEAR CALCULATION OF LIGHT REINFORCED ELEMENTS ACCORDING TO SR EN 1992-1 STANDARD

Abstract

In this work is presented the method used for calculating lightweight reinforced concrete elements in oblique sections according to the SR EN 1992-1. There are presented principles and calculus relations for checking the structural resistance of elements that need reinforcement for shearing force, respective vertical reinforced elements. The results of the experimental testing conducted in the Reinforced and Prestressed Concrete Laboratory of The Constructions and Installations University of Cluj-Napoca for 16 beams of lightweight reinforced concrete have permitted the comparative study between the experimental values (Qe) and the calculated one (Qc cap), of the shearing force. The idea behind this comparative study was the verification of the module in witch the actual designing norms according to SR EN 1992-1 satisfyingly reflects the observed behavior of the elements during the experimental tests.
