Abstract

Any industrial or organised storage facility needs bulk material storage structures, also referred to as bins, bunkers, silos, or tanks. The ratio of their various dimensions serves as the main defining characteristic between bunkers and silos. Silos are structures that are used for storing different types of granular material. Silos are architectural constructions made especially for storing different kinds of granular materials, such grains and cement. Silos are distinguished by their disproportionately tall lateral dimensions. For instance, massive silos are frequently used to store cement in cement mills and significant construction projects. The project's main goal is to analyse and design a silo made of reinforced cement concrete. The theory adopted for analysis of silo is Janssen’s theory. The silo is designed for storing the cement clinkers with a capacity of 5000 tonnes. The normal pressure calculation during emptying and filling, and maximum pressure calculation has performed. The hoop stresses and Temperature stresses are calculated and hoop tension is calculated for different heights. The assessment of the loads on silo was performed as per IS: 4995 (Part I) - 1974, and for design criteria IS: 4995 (Part II) – 1974 is used.
