Hello everyone,
Q1: I want to know whether this format is already correct or not?
Q2: After we define the seismic definition, then we start to add Load Case of seismic first.. Does the PDELTA ANALYSIS command should be written in this load case? or PERFORM ANALYSIS ?
Q3: To obtain the result of all load cases acting concurrently, I use Repeat Load instead of Load Combination. Does it mean that even we don't use PDELTA ANALYSIS command, we'll get the same result since we already use Repeat Load?
Q5: The last command (before FINISH), it should be PDELTA ANALYSIS again or just PERFORM ANALYSIS ?
Please your kindly advice.
Thanks a lot.
Really appreciate your help.
