一种新型行列布置立筒仓的结构力学设计要点

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

立筒仓以容量大、占地面积小、力学性能好等优势成为大仓容储粮的首选,但仓群中星仓积粮和容积小的问题一直以来没有得到很好解决。基于midas Gen2019软件,针对某港区综合码头工程项目立筒仓进行拉大排仓的间距,以短墙连接排仓形成了一种新型筒仓布置方式,通过对7种粮食荷载工况的整体有限元模拟分析,获得了短墙及相邻仓壁的内力分布规律,找出了设计控制工况,为该类布置形式的筒仓设计应用提供了参考。

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.
