Abstract
he total prefabrication of medium-rise r.c. buildings typically consists of large panel structures having high mass and burdensome connections. A discretely-connected innovative light-weight panel element with vertical voids has been invented and patented by DLC Consulting-Milan and studied within a collaboration between Politecnico di Milano and University of Pristina. The structural behaviour of the wall subjected to lateral action has been investigated by means of non-linear analyses with damage-sensitive 2D elements. Such elements allow to estimate the crack pattern and to draw monotonic capacity curves, investigating the effect of different reinforcement arrangements on the structural behaviour of the wall. An innovative solution is also proposed to in-crease the ductility of the wall when subjected to seismic action and heavily reinforced in shear. Furthermore, the efficiency of a simplified beam model of the wall with distributed plasticity is validated against the results from pseudo-dynamic tests performed at the ELSA/JRC laboratory of Ispra (Italy) in the framework of the Safecast project on a full scale prototype of multi-storey precast building being braced by the walls under investigation.
