RINTC-E project: towards the seismic risk of low and pre-code single-story RC precast buildings in Italy

This paper reports the preliminary results of a research project (RINTC-E) aimed at computing the risk of collapse in RC precast industrial buildings designed according to the codes in force in Italy in Seventies and Nineties. Companion papers describe the overall research project, funded by the Italian Civil Protection Department, its different areas of application (reinforced concrete, masonry, steel buildings, etc), and the overall seismic risk calculation procedure. This paper describes the design, modelling and pushover nonlinear analyses of one-story precast RC building, designed according to codes in force in Italy in Seventies. The structural nonlinear behavior is modeled using a lumped plasticity approach and the beam-to-column connection is based on friction forces. Collapse of the building is evaluated considering two failure conditions: i) 50% degradation of the maximum base shear recorded on the pushover curve; ii) beam-to-column connection failure
