Good afternoon,
We have a model introduced in CAESAR II 5.20 such us the load case combination are the following :

W: weight
T1: calculation Temperature
P1: calculation Pressure
WW : water weight
HP : hydrostatique pressure
WIN1 : wind +X WIN2 : wind –X
WIN3 : wind +Z
WIN4 : wind -Z
U1 : earthquake X
U2 : earthquake Y
U3 : earthquake Z D1: Displacement X
D2: Displacement Y
D3: settlement Z negativ
D1= 37.05 ; 0 ; 0
D2= 0 ; 55.95 ; 0
D3= 0 ; 0 : -41
All nodes are introduced with Cnode and we according three independent displacement for this Cnodes D1, D2 and D3
But in the output exactly at case L31=L29+L30 and L35=L32+L33+L34 with SRSS method combination we have a non logical displacement;
Example In one node :
Case L35; DX=41.244mm; DY=56.311mm; DZ=2.113mm
Case L31; DX=41.244mm; DY= 55.999mm; DZ= 0mm
Knowing that the Cnode displacement is the three displacement introduced above
For Z displacement isn’t logic because we have a settlement of -41mm
the vector of displacement is ∆X=41.244-37.05=4.194mm ; ∆Y=56.311-55.95=0.361mm; ∆Z=2.113-(-41)=43.113mm
Can you please explain this confusion? Especially Z displacement
thank you for advance
