摘要:
根据抗震墙结构、梁等以弯曲变形为主的结构和构件的变形特点,假定横向位移相等,提出了一种新的单元——偏八结点等横向位移有限元,通过算例证明其对于以弯曲变形为主的结构和构件,具有所需单元少、总刚小、计算精度高等特点.本文提出的位移相等假定下的总刚集成方法,简单明了,具有通用性.
Abstract:
According to the deformation characteristic of the shear wall or beam which is mainly bending, a new kind of finite element is put forward. It is called partial eight-node element with equivalent displacement. The calculating example proves that to the bending deformation, this element has the character of less elements, small array of general stiffness, and high precision. It is an effective tool for structural elastic-plastic calculation. The method in this paper to form the general stiffness array under the equivalent crosswise displacement is very simple, and can be used to other elements.
