Simulation of Smart 2013 shaking table test with shell elements and PARC_CL modeling

In the paper it is described the simulation of the Smart 2013 shaking table test by means of multi layered shell elements modeling and a total strain fixed crack model called PARC_CL. The shell modeling proved to be quite efficient for structural wall buildings as it can take into account global and local damage indicators. Results in terms of stresses contours, crack openings and floors displacements are then provided for a strong motion earthquake (Run #19 of the test). The same model was used also for the evaluation of fragility curves in Stage 4 of the test: examples are then provided both for linear and non linear runs. The multilayer shell elements modeling demonstrated to be a powerful tool although many issues like damping implementation, sliding shear walls failure mode and computational costs optimization require further studies.
