I am using AQB to calculate the non-linear stresses (NSTR) of beam elements. I would like to store the envelope of the AQB results in 1 Load Case. Usually I use the command “COMB GMAX LCST 98” for this, but it does not seem to work as I am getting the following error:
+++++ error no. 2053 in program AQBEI ; input line: 14
It is not possible to store a new stiffness in the database
for combined load cases
This is the code that I am using:
+PROG AQB urs:53
HEAD PIERS - NON LINEAR STRESS - SLS RARECTRL REIN FIX
