【摘要】 本文利用Love波弥散特性在频域上对地基出平面振动及扭振问题进行了研究。在计算区域内结构将采用有限单元划分,而在边界上则根据Love 面波特性使用传递边界有限单元。本文同时讨论了不同模态波对结构动力响应的贡献。本文方法也适合于静力分析。更多还原

【Abstract】 The out-plane vibration and torsional vibration problems of soil are studied in frequency domain usingLove surface wave characteristic in this paper.The finite elements are used in calculated domain of struc-ture.The transmitting boundary finite elements are used in calculated domain boundary of structrue accord-ing to Love surface wave charateristic.The contribution of different mode waves of the same frequency todynamic response of structure is also discussed in this paper.The method presented in this paper is also ap-plicable to static analysis.更多还原
