When standing because of people, in order to keep balancing, No.1 column 6 and No. four 8 stress of column are larger, as long as so considering this two
Column.
No.1 column 6：
A=8 × 8=64mm2；
ix=0.4h=0.4 × 8=3.2mm；iy=0.4h=0.4 × 8=3.2mm；
lox=loy=17cm；
Because of the higher value of the equal slenderness ratio of x-axis y-axis, so：
X-0.623=9 × (0.616-x)；X-0.623=5.544-9x；
10x=6.167；
X=0.6167；
Therefore the stability of No.1 column 6 is enough.
No. four columns 8：
A=8 × 8=64mm2；
ix=0.4h=0.4 × 8=3.2mm；iy=0.4h=0.4 × 8=3.2mm；
lox=loy=17cm；
The higher value of the slenderness ratio of x-axis y-axis, so
X-0.623=9 × (0.616-x)；
X-0.623=5.544-9x；
10x=6.167；
X=0.6167；
Therefore the stability of No. four columns 8 is enough.
Therefore the model structure of the present embodiment has excellent stability.
