This article focuses on the comparison between the results of non-linear static analysis (NLSA) and non-linear dynamic analysis (NLDA), performed on a benchmark structure by using two different finite element programs (CDS-Win and SAP2000). The benchmark structure was a 3 storey reinforced concrete frame existing building, regular in elevation and plan and located in a high seismic zone. The structure was retrofitted by introducing a hysteretic energy dissipation bracing system sized by means of a Focus–Displacement Design procedure based on NLSA. The NLDA have been performed using a set of artificial earthquakes comprising of 7 spectrum-compatible accelerograms selected in order to match, on average, the design spectra. In order to verify the effectiveness of the CDS-Opensees and to demonstrate its computational advantages in case of r/c building frame with hysteretic bracing system, in this contribution the results of both NLSA and NLDA are detailed.

Abstract

This article focuses on the comparison between the results of non-linear static analysis (NLSA) and non-linear dynamic analysis (NLDA), performed on a benchmark structure by using two different finite element programs (CDS-Win and SAP2000). The benchmark structure was a 3 storey reinforced concrete frame existing building, regular in elevation and plan and located in a high seismic zone. The structure was retrofitted by introducing a hysteretic energy dissipation bracing system sized by means of a Focus–Displacement Design procedure based on NLSA. The NLDA have been performed using a set of artificial earthquakes comprising of 7 spectrum-compatible accelerograms selected in order to match, on average, the design spectra. In order to verify the effectiveness of the CDS-Opensees and to demonstrate its computational advantages in case of r/c building frame with hysteretic bracing system, in this contribution the results of both NLSA and NLDA are detailed.
