Experimental and design loads of pressure of bulk materials against silo wall

Abstract

These investigations were carried out on silo models, free-standing silos and silo batteries. The researches include the evaluation of value of pressure and temperature field on the silo wall as well as temperature gradient, registration of simultaneity of these loads. There were used sensors placed in the silo wall and bottom and sensors placed into material as sounder. The researches include either the evaluation of influences of the strength parameters of wall. Each of these investigated parameters is a random variable. Collection of such data as pressure, temperature, strengthen coefficients is of great significance, so the authors measured these loads many times. There is the need of calculation such quantities of statistics as characteristic, design value of measured loads and strength parameters, material and loads coefficient partial coefficient of safety, reliability indexes etc. These data were subjected to statistical accounts. The data obtained from calculations can be used in designing similar silos and in silo codes.
