【摘要】 在土—结构相互作用体系自振频率的计算中,整体有限元法是一种有效的计算方法。通过一系列算例,对整体有限元法的计算模型中土体单元网格划分、人工边界处理、楼板模型及土体计算宽度的确定等问题进行了计算分析,确定了合理的计算模型参数,并对土体无质量模型进行了验证。更多还原

【Abstract】 The method of integral finite element is efficient in computing the nature frequency of soil-superstructure interaction system.In this paper,the parameters in finite element model are determined through case calculation to analyze the artificial boundary,size of element,floor model and soil width.At last,"with no mass-assigned soil model" is verified through some examples.更多还原
