摘　　要：采用框架核心筒伸臂结构的简化计算模型,将核心筒看做底端固定上端自由的悬臂梁,伸臂对核心筒的约束作用看做抗扭弹簧,考虑核心筒和伸臂的弯曲、剪切变形及核心筒的宽度影响,导出了结构的Hamilton对偶求解体系,通过两端边值问题的精细积分法,求解核心筒的内力与变形。以施加倒三角水平荷载的框架核心筒伸臂结构为例,进行算例计算。In the simplified calculation model of the frame-corewall-outrigger structures,with the corewall regarded as a cantilever beam with the fixed bottom and free top,and with the outrigger's restriction effect to the corewall as a torsional spring.Then,the Hamilton dual system is derived while considering the influence of the bend,shear deformation and the corewall width.The corewall's internal forces and deformation are obtained based on precise integration method of two end boundaries.The calculation model is employed by a frame-corewall-outrigger structure with inverted triangle load.
