I am trying to perform a pushover analysis on a shell group.
I have taken the displacements from the corresponding eigenvalue.
+PROG SOFILOAD urs:18.3 $ PUSHOVER LC
HEAD Pushover LC X
lc 1002 type none titl ‘PUSH-LC-LOAD X disp’
acce type DISP no 0 ax 1 linf -2001
then I cannot perform the analysis. is it performed from ulti?
I am trying:
+PROG ASE urs:9
HEAD WALL ULTI
SYST PROB TH3 NMAT YES
ULTI 20 FAK1 1.0 DFAK 1.0 PRO 2.0 DL no PRIM yes EPSC -10.0
LC 1101 FACD 1 TITL ‘wall th3 ulti’
LCC 1002 FACT 1.0/25.0 ULTi YES
NSTR - KSV UL KSB UL FMAX -
but it doesn’t work. it says:
+++++ error no. 174 in program TFACHLAGER2_CHECK
Support displacement at node No 1 may cause problems if coupling defines a
real fixing in that direction. Inclined couplings are possible but must be checked.
For inclined couplings this error message can be switched off with CTRL WARN 174.
Could you provide an example?
Thank you in advance
