摘要
对某3层中空阁楼已有的结构布置和受力情况进行模态分析,得到结构离散化模型和有限元系统。通过有限元法建立模型、施加荷载,进行静力分析及模态分析,得出相应的自振频率、振型以及板单元应力关系图。分析结果表明:典型3层中空楼阁形式的仿古建筑符合一般建筑平动扭动的规律,其结构形式在抗震上是可行的;每层的应力值随高度的增加而减小,建筑的角点与梁板的边缘处都出现了应力变大的情况。最后根据以上应力变化特点提出了有效可行的改进措施。
Based on existing structural arrangement and stress state of a three-tier hollow attic,its the modal analysis was performed to obtain the discrete structural model and finite element system.A model is formed and the load is applied by finite element method.Static analysis and modal analysis was performed on the finite element model to obtain the natural frequency,the vibration mode and the stress diagram of the plate element.Results indicate that the vibration pattern of the typical three-tier hollow pavilion is similar to the translation and twist of typical buildings.The structure type is seismic resistant.The stresses of each floor decreases with the increase of height.There is a stress concentration on the corner of the building and at the edge of the beam.Effective measures were proposed based on the above mechanical characteristics.
