ON THE CRITERIA FOR THE OCCURRENCE OF LOAD REDISTRIBUTION IN THE SILO FILLER FROM SEISMIC IMPACTS, METHODS FOR DETERMINING PARAMETERS AND THE ASSOCIATED LATERAL PRESSURE

To assess the conditions of occurrence (or absence) of the redistribution phenomenon during seismic impacts in the silo filler, criteria have been developed to assess the factors affecting this and their values: the density of the filler and its compaction potential, the relationship of accelerations and the depth of the compaction zone, as well as sediment. In the absence of calculation formulas, a method for determining precipitation, as well as the duration of exposure with calculated acceleration, based on the use of the results of vibration compression tests of filler samples, is proposed and shown by examples. The methods of calculating the resulting filler pressure on the walls using the author’s formula are shown.
