The dry-assembled wall is provided with lightening vertical hollow cores, while the connection between stacked walls or between the bottom wall and its foundation is made through non-lightened portions of the wall provided with mechanical connections. This technology leaves thin horizontal slots within the wall at each storey. The behaviour of a 3-storey isolated wall under both gravity and lateral forces is studied through non-linear static analyses with a damage-sensitive plate modelling. A comparison is made with reference to the equivalent cast-in-situ wall and to different reinforcement distribution within the precast wall. Furthermore, the results from dynamic non-linear analysis performed on a complete 3-storey office building provided with the investigated precast walls are presented, based on a simplified beam model of the wall. The results are compared with the experimental data from the same prototype building, tested at full scale with the pseudo-dynamic technique at the European Laboratory of Structural Assessment of the Joint Research Centre of the European Commission at Ispra (Italy) within the Safecast project.
