Analysis of the Recorded Response of a School Building Heavily Damaged by the 2016 Central Italy Earthquake

The OSS (acronym of the Italian “Osservatorio Sismico delle Strutture”) is a network permanent seismic monitoring systems installed on about 150 buildings in Italy. Each system consists number sensors sufficient to completely describe dynamic response structure. Structural typologies have been selected according their representativeness public building stock and importance for emergency management. Data available each include: structural survey situ tests materials, experimental modal analysis, finite element models model updating. In above framework, school located Amatrice, small town meizoseismal area heavily impacted by 2016 Central Italy earthquake, one instrumented OSS; thus, its monitored response, including that under main shock, available. showed diffused huge damage with partial collapses. Firstly, linear used interpretation amplitude vibrations order give reliable characterization initial conditions Some relevant quantities recorded motion excitation are behaviour. displacements then applied nonlinear model, numerical results compared evidence. aim discuss capability combined use computational tools quantifying suffered structure basis measured an earthquake.
