钢筒仓结构广泛应用于矿业、冶金、化工、电力、农业等诸多领域中的散料储存。圆形钢筒仓通常由仓筒、锥形漏斗及支承裙筒组成。在仓筒与漏斗的连接处通常设有一道环梁 ,以承受由漏斗壁上拉力的水平分力所产生的周向压力。常见的环梁形式包括环板形环梁、T形环梁以及角钢形环梁。环梁在周向压力作用下的破坏模式包括塑性破坏、弹性屈曲以及塑性屈曲。近年来对于均匀支承环梁的屈曲及破坏强度已有了系统的研究 ,本文将总结这些研究成果并给出一整套设计公式 ,供结构工程师在设计中应用。||Steel silos are widely used for the storage of bulk materials in many industries including mining, metallurgy, chemical, electric power generation and agriculture. A circular steel silo generally consists of a cylinder, a conical hopper and a skirt. The cylinder/hopper junction is subject to a large circumferential compressive force due to the horizontal component of the meridional tension in the hopper, so a ringbeam is usually provided at the junction. Typical forms of the ringbeam include an annular plate, a T-section ring and an angle section ring. Under the circumferential compressive force, the failure modes of the transition ringbeam include plastic collapse, elastic buckling and plastic buckling. Systematic investigations have been carried out on the buckling and collapse strength of uniformly supported transition ringbeams in the recent years. This paper provides a review of these studies and presents a set of design approximations which can be applied in practical design. 还原
