摘要
本文对筒仓结构进行了模型实验研究,在获得大量实验资料的基础上,将散料假定为连续土体,用半解析环元方法进行了分析研究。为了解决散料与仓壁的连接问题,本文建立了接触矩阵,引入了正确的连接条件,使计算结果有了良好的改善。理论分析结果与实验结果的良好吻合表明,本文的方法具有足够的精度。
This paper presents the results of an experimental and theoretical research on seismic behaviour of silo structures. The test results show that the silage has significant influence on dynamic behaviour of silo structures and can be assumed to be isotropic visco-elastic soil in dynamic analysis.To deduce an accurate method for computing seismic response of soil structures, a fictitious contact matrix to treat the contact boundary condition which permits the frictional slide between the silage and silo is proposed.The good agreement between the computed results and the test results shows that the method proposed in this paper is suitable for seismic response analysis of silo structures.
