错层对水平荷载作用下短肢剪力墙受力性能影响的研究

STUDY ON EFFECT OF STAGGERED FLOORS OVER PERFORMANCE OF SHORT-PIER SHEAR WALL UNDER LATERAL LOAD

利用ANSYS分析错层短肢剪力墙在水平荷载作用下的应力分布规律及错层对结构抗侧刚度的影响。分析表明，错层墙肢应力分布明显有别于普通墙肢，且分布复杂；错层对结构的抗侧刚度影响与错层位置、构件刚度比等有关。最后指出错层墙肢是设汁的关键，并建议斜截面抗剪承载力计算公式。

ANSYS is utilized to analyze the stress distribution of short-pier shear wall with staggered-floor under lateral load, and effect that the staggered floors affect the lateral stiffness of the structure is also discussed. It is shown that the stress distribution of stagger-wall is complicated and different to that of normal-wall, and the influence of staggered floors to lateral stiffness of the structure is decided by the location of the staggered floors and the stiffness ration of wall to beam. Lastly, the key importance of properly designing the staggered-wall is emphasized; moreover, formula for calculating shear strength is suggested.
