摘要
借助ANSYS有限元软件,根据实际工程的相关设计原则,对一座12层高的框架剪力墙结构进行了模态分析,得到了主要频率及相关数值模拟参数。其后,又加载了3种常用的地震波,观察并分析了此结构的地震响应结果。结果显示:框架剪力墙结构,在地震作用下有较好的抗震性能,但底部节点及顶层部分节点在一些波形的激振下,弯矩与轴力急剧增大,容易发生破坏,故设计时要特别予以关注。本研究为以后建立多高层实物模型、运用振动台进行实物与数值模拟对比分析奠定了一定的理论基础。
With the ansys finite element software, according to the design principles of practical engineering, a 12-story frame shear wall structure has been set up to have the model analysis, and the main frequency and the related numerical simulation parameters have been obtained. Then with three commonly used seismic waves loaded, observation and analysis of the seismic response of the structure have been carried out. Results show that the frame shear wall structure has a good seismic performance under seismic action, but the bottom nodes and part of the top nodes will be subjected to damage owing to the intensive increase of bending moment and axial force under wave vibration, which calls for special attention in design. The work and analysis provide a theoretical basis for the future establishment of multi-story physical model and comparative analysis between real objects and numerical simulation with the vibration table.
