How to define load combination

How to define load combination

How to define load combination

(OP)
Sorry if this is a simple question, but I am new to ETABS.
In analysing a building after defining the loads (dead, live, wind and earthquake, we also have to define load combinations and choose the sever case for each element based on these load combinations.
How can I define load combinations in ETABS?

RE: How to define load combination

(OP)
I find "Load Combination" command under define menue.
Now my problem is how to assign these load combinations to the building?

RE: How to define load combination

you must see your design code, for example one of the ACI318-99 load combination is 1,4D + 1,7L
then to define this load case you must ADD new combo... then select DEAD Static Load and select as Scale Factor 1,4 then press ADD Button, then select LIVE Static Load and select as scale factor 1,7 then press ADD button

Dear civilungo
Thanks for your reply. I was able to define a load combination as you mentioned. My problem is how to assign this load combination to the structure?

Thanks in Advance

RE: How to define load combination

load combination is just a array of loads cases in your structure that serves to calculate forces, stresses and deflection but you don't have to assign load combination to the structure, you just have to assign loads (DEAD, LIVE, EARTHQUAQUE, ETC) and the load combination are independent from the structure.

RE: How to define load combination

Thanks. I didnt know that. Therefore assigning basic loads (DEAD,LIVE,EQ and wind) will be enough and load combinations will be done automatically.
thanks again
