Non-linear seismic analysis of RC framed building designed according to EC-8

One of the main aims of the design of earthquake resistant structures is to ensure that the design seismic action do not cause local or global collapse of the structure. Eurocode 8 includes prescriptions in order to guarantee ductile behaviour of the structure and its structural elements and adequate bearing capacity. Concrete buildings in high seismic area are classified in two ductility classes DCM (medium ductility) and DCH (high ductility) depending on their hysteretic dissipation capacity. To provide the appropriate amount of ductility, specific provisions for all structural elements shall be satisfied in each class. In this paper five- storey reinforced concrete frame building is studied using nonlinear static analysis and incremental dynamic analysis. The building was previously designed for DCM and DCH ductility class according to the prescriptions of EC-2 and EC-8, accepting the demands of the local ductility. The aim of this paper is the analysis of differences in the behaviour of the structure between these ductility classes. The mechanism of loosing the bearing capacity, collapse loads and behaviour factors obtained by nonlinear static analysis and incremental dynamic analysis were analyzed and compared. A series of seven earthquakes taken from the European Strong-Motion Database, fully satisfying the EC-8 provisions, are used as input for incremental dynamic analysis. The results obtained by non-linear static analysis show higher yield ratio of base shear and building seismic weight for DCM in relation to DCH, while the target displacement and bearing capacity at the collapse is higher for DCH. Behaviour factors for both ductility classes obtained by incremental dynamic analysis and static nonlinear analysis are larger than those demanded by EC-8.
