Correlations between the experimental results of pseudo-static tests with cyclic horizontal load on concrete/polystyrene sandwich bearing panels and their analytical and numerical counterparts

In recent years, the seismic behavior of reinforced concrete bearing squat walls structures has been the object of several research works. This paper presents a summary of the results obtained in a wide experimental/analytical/numerical correlation campaign carried out as a joint effort between the University of Bologna and the EUCENTRE labs in Pavia. This effort was devoted at the assessment of the seismic performances of structures composed of (lightly reinforced) concrete/polystyrene sandwich bearing squat walls. In this paper: (1) the results of a number of pseudo-static tests with cyclic horizontal load have been briefly recalled; (2) extensive analytical developments have been carried out to evaluate the mechanical characteristics and the seismic behavior of lightly reinforced concrete panels; (3) a comparison between the analytical and the experimental results has been performed. The comparison shows a good agreement between the experimental results and their analytical counterparts.
