The paper presents a statistical description of the values of random variables of pressure and temperature as the most important loads on wall of silo, in which hot materials, such as cement, clinker, fly ash, and raw meal are stored. An attempt to statistically describe the pressure and temperature and their additive share in loads are clearly present in the standards and guidelines for reinforced concrete (RC) silo design. The authors conducted many experiments and measurements of pressure and temperature that impact on the silo walls. For example, in a silo for a hot cement, variable pressure and temperature of the silo wall were measured simultaneously. In this example, coincidence coefficients for temperature and pressure were calculated using many statistical methods. For the pressure, a statistical determination of characteristic values was proposed.
