摘  要:
通过对框架式筒中筒结构的钢模型试验,建立计算模式。将侧力作用下的框筒变形分解为弯翘效应和剪切效应两个独立部分,写出总势能泛函。引入单位曲率,从而先算出轴向翘曲位移模式,使推出的连续化位移法控制微分方程大为简化。算例表明本文算法是可靠和实用的,可供初步设计应用。

摘  要:
With the steel model test of framed tube—in—tube structure, the calculated model is established. The deformation of framed tube affected by lateral load is divided into the bending—warping effect and the shear effect. The differential equations of general potential energy with continue displacement method are derived. These equations are made to be very simplified by introducing the unit curvature and deducing the model of warping displacement first. Compared the calculated solution with the test results, it is shown that the method can be applied to the primary design.
