please to see the PIC for the model

when I calculate a pipe model,I find the diffence of the Global element Force and restraint summary for the same case and node, please to see the result:

CASE 46 (OPE) W+D4+T1+P1+H-U1+F1

Global element Force
FX(N) FY(N) FZ(N) MX(N/M) MY(N/M) MZ(N/M)
1261 -60486 -278988 43800 -9483 0 -13120
1262 60715 279753 -43800 0 0 0

restraint summary
FX(N) FY(N) FZ(N) MX(N/M) MY(N/M) MZ(N/M)

46 (OPE) -60715 -279753 46190 0 0 0
I Think :46190=60715*0.3+279753*0.1

but 60715*0.3+279753*0.1≠43800

(43800-46190)*100/46190=5.17% is this the calculation error ?

who can help me deal with this question?
thanks lot
