摘要
采用沿高度方向连续化的方法,建立了框架-剪力墙-薄壁筒斜交结构自由振动分析的连续化计算模型。将沿高度方向的坐标虚拟成时间坐标,导出了问题的状态空间表达式,用状态空间理论的方法求出了状态向量表达式,由结构的边界条件可求出初始状态向量,从而得出结构的自振频率。给出了数值算例,并与其他算法的结果进行了比较。
By use of the uniformization technique, a continuous model is developed for the analysis of frame-shear wall-thino walled core skew combined structures. By simulating the space coordinate along the height direction of the structure as the time coordinate, the state space equations are derived. The state vector equations can be calculated according to the state space theory and initial state vector can be obtained. Then the free vibration frequency of the structure can be derived from the bondary conditions of the structure. Compared with other methods, the numerical results demonstrate that the proposed method is simpler to compute, more accurate, and more convenient for application.
