摘要
提出一种变截面筒中筒结构的简化计算方法 ,其要点是对结构平衡微分方程采用初参数解 ,通过边界条件求出初参数解 ,然后由矩阵递推算出水平荷载作用下内外筒的变形和内力。用此方法分析变截面筒中筒结构 ,不会因为楼层层数的增加而增加结构控制微分方程的未知量 ,计算简单易行 ,并可获得满意的计算精度。
This paper puts forward a simple calculating method of tube in tube structures with variable sections. The key points are as follows:According to the differential equation of the structure balance and using the initial parameter solution that can be got through the boundary condition and transferring of the matrix. So the displacements and the internal forces of the internal and external tubes can be obtained. And it will not increase the unknown quantity of control differential equation with the increase in the number of layers, with which a good accuracy is also got. So it is simple and convenient.
