Dear members,
Can you help me in making difference between Repeat Load, Load combination and Reference load. What is the appropriate position of assigning these loads.
Furthermore, how can we assign the negative sign in load combination?
Waiting for your valid response.

You asked :
Can you share as how can we assign negative sign in Load combination and Repeat Load in Staad Pro v8i. For example, what is the correct way of assigning laod case of 1.2(0.9D-EQX) in load combination & Repeat Load.
Answer :
If we assume that the Dead Load case is load case 1, and the earthquake load case is load case 7, then,
1.2(0.9D-EQX)
reduces to
1.08 * Load case 1 - 1.2 * Load case 7
The Repeat Load syntax would look like this
LOAD 31 1.2(0.9D-EQX)
REPEAT LOAD
1 1.08 7 -1.20
The load combination syntax would look like this
LOAD COMBINATION 41 1.2(0.9D-EQX)

Regarding your question on Reference Load
Have you read sections 5.31.6 and 5.33 of the Technical Reference manual? Let us know if those do not have the informaton you are looking for.
Dear Mr. Kris Sathia,
