框架结构由于一层层高较大,且基础埋置较深,计算模型一层层高6.5米,而2~5层层高只有3.6米,这就造成计算模型竖向不规则。如下 =========================================================================== Ratx,Raty : X,Y 方向本层塔侧移刚度与下一层相应塔侧移刚度的比值 Ratx1,Raty1 : X,Y 方向本层塔侧移刚度与上一层相应塔侧移刚度70%的比值
Ratx,Raty : X,Y 方向本层塔侧移刚度与下一层相应塔侧移刚度的比值
Ratx1,Raty1 : X,Y 方向本层塔侧移刚度与上一层相应塔侧移刚度70%的比值
或上三层平均侧移刚度80%的比值中之较小者
RJX,RJY,RJZ: 结构总体坐标系中塔的侧移刚度和扭转刚度

===========================================================================
并且计算结果显示一层抗剪强度小于剪力(如下)。请教高人此时是否程序自动把一层地震剪力按规范放大1.15倍,还是要手动调整某些参数;另外像下面显示的抗剪强度不足,应该如何去调整,还是不用去管他?谢谢! Vx, Vy ----- The Shear Force of Floors (层剪力)
