本帖最后由 jishiman 于 2015-4-20 09:33 编辑 一18层框剪,发现第4层的Ratx2,Raty2输出结果有问题!根据Ratx2=本层的RJX3/H÷上层的RJX3/H的90%,第4层的Ratx2=(2.4394E+05)÷(0.9*3.3102E+05)=0.8188,但输出结果却是Ratx2= 1.2794!这是为什么啊?对比发现,层高改变的地方,计算的都不对啊,像1层、17层。
一18层框剪,发现第4层的Ratx2,Raty2输出结果有问题!
根据Ratx2=本层的RJX3/H÷上层的RJX3/H的90%,
第4层的Ratx2=(2.4394E+05)÷(0.9*3.3102E+05)=0.8188,
但输出结果却是Ratx2= 1.2794!这是为什么啊?
对比发现,层高改变的地方,计算的都不对啊,像1层、17层。
【根据楼层剪力,平均层间位移,两者相除,发现RJX3/H、RJY3/H都是正确的】
以下是输出结果:
===========================================================================
各层刚心、偏心率、相邻层侧移刚度比等计算信息
Floor No : 层号
Tower No : 塔号
Xstif,Ystif : 刚心的 X,Y 坐标值
Alf : 层刚性主轴的方向
Xmass,Ymass : 质心的 X,Y 坐标值
Gmass : 总质量
Eex,Eey : X,Y 方向的偏心率
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(剪切刚度)
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
Ratx2,Raty2 : X,Y 方向本层塔侧移刚度与上一层相应塔侧移刚度90%、110%或者150%比值
110%指当本层层高大于相邻上层层高1.5倍时,150%指嵌固层
RJX1,RJY1,RJZ1: 结构总体坐标系中塔的侧移刚度和扭转刚度(剪切刚度)
RJX3,RJY3,RJZ3: 结构总体坐标系中塔的侧移刚度和扭转刚度(地震剪力与地震层间位移的比)===========================================================================
