Smart 2008: Experimental Test of a Reinforced Concrete Building Subjected to Torsion

Abstract eng:
Reinforced concrete buildings exhibiting 3D (i.e. torsion) and non-linear effects are a main concern in the field of earthquake research and regulation. In the last decade, several reinforced concrete specimens have been tested under seismic excitations in order to study the seismic behaviour of shear walls, but without significant 3D effects. In order to assess the capability of structures exhibiting 3D effects to withstand earthquake loads as well as seismic loads induced to their equipments, a reduced scaled (1/4th) model of a 3 stories reinforced concrete structure with 3D effects will be tested between June and September 2008 as part of the SMART project on AZALEE shaking table (EMSI Laboratory – CEA Saclay – France). The aim of this project is (1) to compare and validate approaches used for the dynamic responses evaluation of RC structures subjected to earthquakes and exhibiting both 3D (torsion) and non-linear behaviours, (2) to evaluate loads induced to internal equipments, (3) to quantify margins in design methodologies and (4) to carry out realistic methods to quantify variability in order to produce fragility curves. This paper presents the main characteristics of SMART specimen, the instrumentation and the seismic tests program, as well as some preliminary experimental tests’ results.
