Key Concepts of Structural Mechanics Design for a New Type of Vertical Silo Arranged in Rows and Columns

Abstract

Vertical silos have become the first choice for large silos to store grain due to their large capacity and small footprint. However, the problem of grain accumulation and small volume in star silos has not been well resolved. Based on the midas Gen2019 software, this paper expands the capacity of the silos for a comprehensive terminal project in a port area, and connects the silos with short walls to form a new silo layout. Through the overall finite element simulation analysis of 7 kinds of grain load conditions, the internal force distribution law of the short wall and the adjacent warehouse wall is studied. and the design control conditions are found, which provides a reference for the silo design of similar type of layout.
