IMK deterioration input parameters for HSS columns

Postby alirezatabriz » Mon May 02, 2016 1:09 pm

Hi,
I have two question about concentrated plasticity concept with rotational springs.
1. I have a 3bay frame. the bays are 5m. Dead and Live loads are equal to 650 kg.f/m^2 and 200 kg.f/m^2 on the floor area and loading width of the frame is 5m. How much of the gravity loads must be assigned to the beam-column joint nodes and How much of the gravity loads must be assigned to the leaning columns? I dont understand the opensees example << Pushover Analysis of 2-Story Moment Frame >>.
2. In the regression equations that suggested by Lignos and Krawinkler for HSS columns how much axial force should be inserted in the equations?

Dead and Live loads are equivalent to 650 kg.f/m^2 and 200 kg.f/m^2 on the floor territory and stacking width of the casing is 5m http://www.essaybox.co.uk/

Hi Alireza
Is your problem solved in relation to the axial load parameter in the Lignos and Krawinkler thesis?
I also encountered a problem like you.
I do not know the value of the axial load ratio parameter in hollow square tube section formulas.Can you help me ?
thanks
