Abstract

In this study the magnitude of reduction in total active pressure, hoop thrust at the bottom level and its distribution after using relief shelfs at junction of chamber of hopper bottom. Silo is considered as the member which is subjected to hoop thrust like water tank. Numerical study is conducted to investigate the effect of the number of shelfs, wall rigidity, vertical pressure, horizontal pressure and its dynamic effect’s. Pressure quantity, the maximum acting bending moment and shear force on the wall are also discussed to perform the designing process. Currently numerical analysis is the time savior method, it will also reduce the money which will used in the experimental work. According to the analysis it was found that relief shelfs have excellent effect on the spreading of the internal pressure or hoop thrust. The numerical result show that relief shelfs used inside the silo would result in reduction of the internal pressure or hoop thrust also also result show that the shelfs plays a positive role as pressure distributor for silo.

Key Words: Bunker & Silo, Effective dynamic pressure, Rupture surface, Single, Double, triple Relief shelfs, Effective design, Best location.
