Research of Light Concrete Precast Lintels

The paper presents the results of precast lintels made of AAC with a total length 2.0 m. The study was divided into two series of basic and general. In the basic series, lintel was studied according to the recommendations of codes EN 846-9: 2002 and EN 1356: 1999. In the general series consisting of the 6 models, lintels with an interacting wall of varying heights were examined. During the test, forces, displacements and deformations were measured using inductive transducers forces and displacements. The basic and the general series demonstrated, among other things, that the destruction of the elements followed in the zone of supporting due to shear.
