Seismic response of grain-silos still presents strong uncertainties and open issues. For this reason, seismic design of silos is not yet consolidated as the design in static conditions (filling and discharging scenarios) and current design codes tend to provide too conservative formulations for the estimation of the seismic actions induced by the stored material. Experimental tests have been conducted during the last decades, including shaking table tests on scaled models for better understand the coupled behaviour of grain-silos. Recently, the authors proposed a theory for the evaluation of the horizontal seismic forces exerted by granular material on silos. The main purpose of the present study is to provide a set of simplified code-like formula for the evaluation of the seismic horizontal forces acting on the silo wall and to compare them with the results of experimental shaking-table tests and with the actual code provisions. |
