摘要
采用沿高度方向连续化的方法,建立了框架-剪力墙-薄壁筒斜交结构协同分析的连续化计算模型。将沿结构高度方向的坐标模拟成时间坐标,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,从而得到了结构各单元的侧移与内力。给出了数值算例,并与其他算法的结果进行了比较。这种结构计算方法计算量小,精度较高,便于应用,能方便地推广应用于变截面建筑结构。
By use of the uniformization technique, a continuous computational model is developed for the analysis of frame-shear wall-thin walled core skew combined structures. 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 the initial state vector can be obtained from the boundary conditions of the structure. Then the displacements and internal forces of each member of the structure can be derived as well. Compared with other methods, the numerical results demonstrate that the proposed method is simpler to compute, more accurate, and more convenient for application. It can be applied to structures of non-uniform sections conveniently.
