000019510 520__ $$2eng$$aHousner published his classical paper in 1963 for the calculation of a rocking block. He assumed that impact occurs at the corners of the block and identical angular momentum before and after the impact. Based on these assumptions he derived expressions for both the energy loss, and the change in velocity. This model is widely used for modeling of stone and masonry columns and arches. Researchers also developed the so called ‘overturning acceleration spectra’ for the verification of blocks, columns and arches subjected to earthquakes. In all these cases the basic element of the calculation is Housner’s classical model. Note, however that experiments – as published in several papers – show lower energy loss during impact than it is predicted by Housner’s model. As a consequence, the overturning acceleration spectra based on Housner’s model may be unsafe. In this paper we discuss the effect of the overprediction of the energy loss of Housner’s model. Furthermore, the effect of the shape of the applied acceleration is investigated.
