Change load coefficient

Anonymous

Hi!

 

I wonder how I can change the load coefficients for dead load?

I need it to be 1 in my type of contruction.

 

Thanks!

I assume you want to generate load combinations automatically. If so I can think of three options:

 

1. Modify the regulation file and generate either automatic code combinations or manual combinations

 

2. Generate automatically manual combinations according to the regulation file as it is and then edit the combinations changing the load factors for dead loads in the combination table.

 

3. Generate automatically manual combinations according to the regulation file as it is.

Create additional manual combination which includes all dead load cases with negative factor (assuming that the load factor for dead loads is e.g. 1.2 the negative factor will be -0.2)

Add this new combination to the automatically crated ones

I'm continuing here when it has to do with the same thing..
I got the coefficients changed but result doesn't change at all..

(I'm trying to calculate the amount of req. rein. in walls and roof in a case where the coefficients needs to be 1)

what's wrong?

What results do you mean exactly?

Can you see the difference in the values of forces for combinations? Is the reinforcement at the minimal required level?

I don't really know what you mean but I can see a difference in the Load combination table that the coefficient is changed.. and no the reinforcement is not on the minimal required level it is higher.

Could you attach the file and screen captures which shows which wall you design as well as which load factors you modified?

Here is the file!

 

Never screen captured before, dont know what to fill in..

 

But it is Wall nr 2 and Floor 1 and i changed the deadloads to COMB1 with the coefficient 1.

As you want to see the influence of load factors defined for ULS combination I switched off the SLS part in the reinforcement parameters assigned to this wall. As you can see the increase of load results in increase of reinforcement.
