摘要
采用脉动法对某框架剪力墙结构的教学实验楼进行动力特性测试,获取结构的模态参数;基于ANSYS分析软件,建立结构三维有限元模型,在考虑和不考虑填充墙两种情况下,分别对结构进行模态分析;对比计算结果,实测结果和考虑填充墙的模型吻合较好,分析影响动力特性的因素,由于填充墙刚度的影响,结构的频率明显变大,振型位移曲线,则更偏于剪切型,其中对纵向影响更明显。其研究成果对今后其他的同类工程具有一定的参考价值。
Field test of dynamic properties of frame—shear structure were carried out,including natural vibration frequency and modes,by using the ambient vibration test technique.And build modes by ANSYS.The comparisons between test dynamic properties and calculated dynamic properties are made to study the influence of infill walls.Results indicate the stiffness effect of infill walls makes the natural vibration frequency of the structure increase and change modes of the structure.The results of its have certain refe...
