摘要
高层结构在竖向荷载作用下,产生框架柱与剪力墙的弹性竖向变形差以及由变形差引起的结构附加内力。通过实例计算表明框架承担的内力有所增大,剪力墙承担的内力减小。框架梁顶部在墙一端负弯矩大、柱一端负弯矩小,同时提出减少竖向差异的措施。
When considering vertical load,high-rise structure will produce differences of elastic vertical deformation in both frame column and shear wall.This vertical deformation will cause additional internal structure force.Through example calculation,the paper indicates that the internal force in the frame bear will become larger,while the internal force in the shear wall will become smaller.On the top of frame beams,the negative moment in the wall side is big,in the column side is small.The paper has put forward some measures on how to decrease the vertical differences.
