Modellazione ad elementi finiti e analisi della capacità sismica per alcune tipologie di strutture prefabbricate monopiano

The paper approaches the problems of the seismic vulnerability of precast structures discussing the aspects of their numerical modelling. The vulnerability of these structures is mainly due to the technological solutions adopted for the connections between structural elements. Therefore numerical analyses take into account different connection models. Typical geometries have been considered and some suggestions are offered dis-cussing the results of numerical analyses in the linear and nonlinear field.
