This paper aims to present studies of various structural alternatives for precast concrete walls for horizontal silos considering the implementation of actions caused by the earth pressure of the stored products. The Horizontal pressure was determined by the GOMES (2000) model. Determining the displacements and the bending moment through the finite element method, manufacturing costs and presents the results of each panel type studied and compares the results obtained. Six types of panels with the same concrete volume: flat panel bi-supported, panel with exposed edges beans bi-supported, and panel TT bi-supported, flat panel bi-supported and supported by floor, panel with exposed edges beans bi-supported and supported by floor and panel TT bi-supported and supported by floor. These panels were considered initially as vertical slabs with horizontal load subjected to two conditions of support: simply supported on two pillars precast reinforced concrete and simply supported on two pillars precast reinforced concrete floor and the horizontal silo through embed hardware. The concrete columns and floors were admitted no displacement. The studies conducted in this work indicate that the panel bi-supported had the highest simply supported had the biggest displacement. The panel with exposed edges beans bi-supported and supported by floor was the alternative structure which had the lowest maximum displacement and the flat panel simply supported and supported by floor was the lower cost alternative manufacturing. The flat panel bi-supported presented excessive displacement in the higher loading.
