摘要:
使用ANSYS软件对一大直径预应力混凝土圆形储煤筒仓结构建立了有限元模型,以储料质量沿高度分布不变为原则,采用施加质量单元的方法模拟储料的分布,通过对预应力混凝土筒仓进行地震作用下的受力、变形分析,研究了预应力混凝土筒仓结构的受力性能及整体抗震性能,同时分析了筒仓结构地震作用简化计算方法的可行性。分析结果表明,水平地震作用对筒仓预应力结构部分的环向力无显著影响,预应力筒仓结构具有良好的抗侧力性能;同时,在结构基本振型指数选取合理时,采用底部剪力法估算筒仓水平地震作用是可行的。所得结果可为同类筒仓结构的地震反应分析提供参考。
Abstract:
The finite element model of large diameter prestressed concrete circular coal silo was built by software ANSYS.Based on the assumption of constant mass distribution of stored material in height direction, the applying mass element method was used to simulate distribution of stored material.The force and deformation analysis of prestressed concrete silo under earthquake load action was carried out.The mechnical and seismic performances of prestressed concrete soil structure and the feasibility of simplified calculating method for earthquake action were analyzed. The results show that horizontal seismic action has not obvious effect on circumferential stress of prestressed components, the prestressed concrete silo has a good lateral force-resistant performance.when the choice of fundamental modal coefficient is reasonable,the evaluation of horizontal seismic action with base shear method is feasible.The results presented could give a reference to seismic analysis of similar siloes
