SMOOTH-ROCKING OSCILLATOR UNDER NATURAL ACCELEROGRAMS [PDF]

Proceedings of the VII European Congress on Computational Methods in Applied Sciences and Engineering (ECCOMAS Congress 2016), 2016
Following the work by Psycharis [1], in this paper we study the dynamic behavior of a rocking block resting on an elastic Winkler-type foundation for the out-of-plane seismic assessment of masonry walls. The equations of motion are derived and implemented for the simple smooth-rocking block and the calibration of the Winkler-type foundation stiffness ...
