关于RATX1和RATY1的调节问题，百思不得其解！

RATX1和RATY1定义为本层侧向刚度和上层侧向刚度的百分之70之比。那么我个人理解想要增大他，需要加强本层侧向刚度，削弱上层侧向刚度。

然而实际计算起来和自己想的大不相同。。新手求解释~~



长条形的结构，二层X方向主梁均为250X800。。这样算出来的结果是：

Floor No. 2 Tower No. 1 Xstif= 5.8500(m) Ystif= 56.8205(m) Alf = 45.0000(Degree)
Xmass= 5.6942(m) Ymass= 56.8625(m) Gmass(活荷折减)= 781.8527( 684.6391)(t)
Eex = 0.0088 Eey = 0.0024
Ratx = 0.4706 Raty = 0.4706
Ratx1= 1.0399 Raty1= 1.0187
薄弱层地震剪力放大系数= 1.00

而我增加了梁高，全部加到250X900之后，结果的RATX1和RATY1却减小了，直接出现薄弱层：:L


Floor No. 2 Tower No. 1
Xstif= 5.8500(m) Ystif= 56.8205(m) Alf = 45.0000(Degree)
Xmass= 5.6953(m) Ymass= 56.8622(m) Gmass(活荷折减)= 787.6376( 690.4240)(t)
Eex = 0.0087 Eey = 0.0023
Ratx = 0.4706 Raty = 0.4706
Ratx1= 0.9965 Raty1= 1.0191
薄弱层地震剪力放大系数= 1.25
RJX1 = 1.0120E+06(kN/m) RJY1 = 1.0120E+06(kN/m) RJZ1 = 0.0000E+00(kN/m)
RJX3 = 1.2999E+05(kN/m) RJY3 = 1.3485E+05(kN/m) RJZ3 = 0.0000E+00(kN/m)


那只能是我理解出错误了，希望高手们给我开解迷惑:handshake
