摘　　要：采用分段连续化的方法,将变截面框架-剪力墙结构简化为多阶剪弯梁,并假定竖向荷载作用在楼层位置处,对每一楼层建立考虑二阶效应时的微分方程,导出了每一层结构的传递矩阵,建立了对整个结构进行二阶效应分析的初参数法,可求出任一截面的变形和内力。最后给出了算例。Using the piecewise continuum technique for floor slabs,the frame-shear wall structure with stepped parameters is simplified as a shear-bending beam with stepped sections,and the vertical loads are assumed to be placed at the height of floor slabs.The differential equation of second-order analysis is derived of every storey,and its transfer matrix is obtained.Thus the initial parameter method is set up,and the deformations and internal forces of the structure can be obtained.An example is also provided.
