The property values that you used for the user defined table does not seem to be consistent with the units. Most likely you intended to use MM KN as units for the user table section C125X65X15 instead of METER KN
START USER TABLE
TABLE 2
*UNIT METER KN - should be replaced by the next line
UNIT MM KN
CHANNEL
C125X65X15
1818 125 5.5 65 9.5 4.66712e+006 786815 43031.5 22.9597 687.5 823.333
Few additional observations
1. Since you have used MEMBER TENSION you should be using REPEAT LOADs as opposed to LOAD COMBINATIONs
2. If you intended to release major and minor axis moments for members, you should release MY MZ as opposed to MX MY.
