Refined NSA approach for seismic assessment of regular RC frames

Szabolcs Varga, Cosmin G. Chiorean

Abstract

The nonlinear time-history analysis of multiple-degree-of-freedom structures is often a time-consuming and impractical procedure. A new computer method, developed in the framework of the Eurocode 8 is proposed in this paper. It is based on the determination of both structural capacity - using pushover analysis - and seismic demand - using nonlinear time-history analysis of a single-degree-of-freedom system. An emphasis is placed on the effect of different lateral load distribution on capacity determination, and on the effect of hysteretic models on the determination of seismic demand.

Keywords
pushover analysis, hysteretic models, constant strength inelastic spectrum, constant ductility inelastic spectrum
