N2 - In this work we present a theoretical study, based on the continuum approach, of the traction forces on the wall of the silo and on a cylindrical rod located at its center when the silo is filled with a dry, non cohesive granular material. We derive expressions for the traction forces by using the Janssen model and the modified, two-parameter Janssen model in order to take into account the existence of dead zones, i.e., the existence of zones without traction occurring during the incipient filling of the silos. Comparison between both models allow understand important aspects observed in experiments.
