摘　　要：多层接地框架是山地、丘陵地区多见的一种结构形式,但以往对其抗震性能研究不是很多。利用二次开发后的ANSYS对多层接地框架抗震性能进行了上下部共同作用分析,发现多层接地框架的抗震性能受到地基情况的明显影响。The frame connected with ground by not only first floor often appears in mountanious region. But the study of its seismic capability is seldom done. In this thesis studies on such frame＇s seismic capability are completed by the ANSYS after secondary development. It has been found out that such frame＇s seismic capability is strongly influenced by the steep slope of ground.

关 键 词：多层接地框架 ANSYS 上下部共同作用 多次透射边界
