摘　　要：根据结构连续化分析方法,采用完备的三角函数系形式表示六边形核筒悬挂建筑结构中筒体在水平力作用下的位移函数,并推导出核筒中剪力墙的正应力和剪应力公式。在此基础上,得出核筒各部分的应变能。而后,根据最小势能原理,得出水平力作用下核筒关键点处的翘曲位移值。由此,推导出了核筒侧向位移及任意指定点的应力、应变和连梁的弯矩及剪力等。最后,分别采用文中方法和有限元软件ANSYS9.0对一个算例进行了计算,计算结果验证了连续化方法的有效性和高效性。提出的连续化方法可以为工程实践计算提供一定的参考。By the continuous method,the displacement shape functions are constructed with the self-contained trigonometric function series,and then the formulae of normal stress and shear stress in the shear walls of the core tube subjected to a horizontal force are brought forward.Therefore,the formulae of the strain energy in each part of the core tube are obtained.Consequently,the warp displacement values of the key points could be found by the principle of minimum potential energy,so that the lateral displacement value,the stresses and the strains of the designated points,and the bending moments and the shear forces in the beams of the core tube will be obtained.At last,the validity and high efficiency of the continuous method are proved by an example,wherein the results obtained by the continuous method being compared with that obtained by the FEM software ANSYS9.0.Wherefore,the continuous method can be used in practical engineering.
