框架填充墙结构的动力试验研究
ynamical experimental and Analytical Study of infilled frames
在实验室条件下对一个四层两跨两开间的1/3框架填充墙模型进行了模态试验，获取了结构的动力参数。试验与分析表明影响结构固有频率的因素很多，其中填充墙的数量、填充墙的位置、填充墙与框架之间的连接方式等为关键因素；采用平面有限元程序与梯度法计算墙体刚度的折减系数。结果表明弹性条件下，填充墙的刚度折减呈上轻下重的近似线性分布。
his modal experiment was run based on a two spans two bays four stored-filled frame with two spans two bays in laboratory. The experiment and analysis showed that among many factors influencing the modal frequency of a construction. The key factors were the quantity and position of masonry and the connect between frame. the plane finite element program and grads method to calculate the stiffness deduction coefficient of the wall. Result showed that in elastic condition, the deduction coefficient distributes linear approximately.
