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。
According to the method of continuous structural analysis, the complete trigonometric system is used to represent the displacement function of the cylinder under the horizontal force in the hexagonal core-tube suspended structure, and the normal stress and shear stress formula of the shear wall in the nuclear cylinder are deduced . On this basis, we can get the strain energy of each part of the core tube. Then, according to the principle of minimum potential energy, the warp displacement value at the key point of the core tube under horizontal force is obtained. From this, we deduced the stress and strain of the lateral displacement of the core tube and the bending moment and shear force of any given point. Finally, an example is calculated by using the method in the text and the ANSYS9.0 software, respectively. The calculation results verify the effectiveness and efficiency of the continuous method. The proposed continuous method can provide certain reference for engineering practice calculation.
