The basic version allows the modeling and analysis of ordinary masonry buildings by separately analyzing the first-mode mechanisms (out-of-plane collapse of the masonry walls) from the second-mode mechanisms (in-plane collapse of the wall). It also allows the estimate of the seismic vulnerability. With the “Mixed Structures” module it is possible to simulate the non-linear response of buildings in a mixed masonry – reinforced concrete structure, taking into account the interaction of the masonry with beams and pillars in a widespread manner.
