This paper shows the results of a nonlinear dynamic analysis of a fixed base reinforced concrete 2D frame subjected to near-field earthquakes, i.e. seismic motions recorded close to the epicentral area of the fault rupture. In these areas both the acceleration and velocity signals are impulsive and consequently the response of the structures requires a specific study. The R.C. frame here considered has six levels and two equal spans; it has been designed according to the instructions provided in Eurocode 2 exclusively under gravity loads, as lots of the existing buildings. The nonlinearity of the frame has been assumed with a diffuse plasticity and a fiber modeling has been considered for the structural elements

Abstract
This paper shows the results of a nonlinear dynamic analysis of a fixed base reinforced concrete 2D frame subjected to near-field earthquakes, i.e. seismic motions recorded close to the epicentral area of the fault rupture. In these areas both the acceleration and velocity signals are impulsive and consequently the response of the structures requires a specific study. The R.C. frame here considered has six levels and two equal spans; it has been designed according to the instructions provided in Eurocode 2 exclusively under gravity loads, as lots of the existing buildings. The nonlinearity of the frame has been assumed with a diffuse plasticity and a fiber modeling has been considered for the structural elementsI documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
