摘要:
在传统的基于集中质量矩阵的剪切质点系法(集中质量法)基础上,发展了基于一致质量矩阵的剪切质点系法(一致质量法),利用剪切质点系法对半空间上水平层状场地自振频率特性进行了分析,主要考虑了土层剪切模量分布、土层层厚分布以及覆盖层总厚度3个因素对场地自振频率的影响,并总结了影响规律,同时考虑了计算厚度选取的问题。分析结果表明:所得结论对于建筑场地地震分析、结构抗震以及剪切质点系法的工程应用均具有一定的实际意义。
Abstract:
On the basis of traditional shear particle system method(lumped mass method), a new shear particle system method based on consistent mass matrix(consistent mass method)was developed. Then, natural frequency characteristics of horizontal layered soils were analyzed with shear particle system method. The distribution of soil layer shear modulus and thickness and the total thickness of soil layers were considered and the influencing law was summarized. At the same time, the problem of computing thickness was considered. The analysis results show that the conclusions have practical meanings to field earthquake analysis, structure earthquake-resistance and apply of shear particle system method.
