【摘要】 由许多小壳单元凝聚而成的四边形组合剪力墙单元,专门用于剪力墙的力学分析.单元的外边界上的4个角结点带有平面内的转动自由度,并且每条外边界上有2个中间结点的位移是由两端正角结点位移的Hermit插值表示.组合剪力墙单元的优点是:(1 )高精度,一个单元可以模拟一个开间的剪力墙;(2 )容易处理开洞引起的一些问题;(3)与梁柱单元位移模式协同更多还原

【Abstract】 The quadrangle assembled shear-wall element was assembled by many small shell elements.It is special for the analysis of shear-wall.The four corner nodes on the outer borders have rotation freedom in the plane.The shapes of the outer borders were decided by Hermit interposition of these nodes.The advantages of this element are:(a)high accuracy,namely one element can imitate one span wall.(b) dealing with the holes on wall easily.(c) cooperating with beam’s mode.更多还原
