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?
