请教ANSYS中偏移问题(附图)

missdaisl

我建了一个框架模型, 在设置柱偏心对齐时,不管怎么样改都不能使左右柱相反,截面设定的程序如下:
SECTYPE,20,BEAM,RECT ! 右边柱
SECOFFSET,USER,0,-0.025
SECDATA,0.85,0.85
SECTYPE,21,BEAM,RECT
SECOFFSET,USER,0,0.025
SECDATA,0.75,0.75
SECTYPE,22,BEAM,RECT
SECOFFSET,USER,0,0.075
SECDATA,0.65,0.65
SECTYPE,23,BEAM,RECT
SECOFFSET,USER,0,0.100
SECDATA,0.6,0.6
!------------------------------------
SECTYPE,24,BEAM,RECT ! 左边柱
SECOFFSET,USER,0,0.025
SECDATA,0.85,0.85
SECTYPE,25,BEAM,RECT
SECOFFSET,USER,0,-0.025
SECDATA,0.75,0.75
SECTYPE,26,BEAM,RECT
SECOFFSET,USER,0,-0.075
SECDATA,0.65,0.65
SECTYPE,27,BEAM,RECT
SECOFFSET,USER,0,-0.100
SECDATA,0.6,0.6
拿以上程序来说,比如20和24号截面,他们偏离Z轴的数据符号是相反的,按理得到的截面应该是相反的(刚好左右柱与外墙对齐),可是如图示左右柱都是一个样子,不管左右柱数据符号互换还是一样,小弟对ANSYS才入门,这一块头都大了,请教高手或斑竹解答一下,万分感谢,我很急!
