With the element, Infill Wall Model and Element Removal, I can do the Pusch over a frame?

my structure is concrete and I modeled the beams with BeamElementWithHinges. I have not included in the initial analysis of the torsional stiffness in the fiber section and the period was 0.8 [s]. After I inserted the torsion (Ubig) and my period is increased.

when I use the wipeAnalysis?

I want to understand the meaning of kinti - kcomm - kcurrent in dynamic analysis with rayleigh.
When I want to do an analysis without damping I put in all zeros, OpenSees which uses initial stiffness?

The concrete compressive strnght at 28 days is cubic or cylindrical?

Which uses opensee stiffness in non-linear analysis of non-linear elements?
Which is the parameter to vary the stiffness?

When I register my accelerogram in the file. AT2, can I write it in a single column?

I made my reinforced concrete frame with two spans two floors and stuck to the base. I want to set up the diaphragms stiff and I used the dof equal in x direction as follows, equalDOF 21 22 1; equalDOF 21 23 1; equalDOF 31 32 1; equalDOF 31 33 1; equalDOF 41 42 1; equalDOF 41 43 1. I applied the mas...

I'm doing a nonlinear analysis with accelleregramma of a reinforced concrete frame. I used non-linear elements and sections in fiber concrete01 and steel02. When I calculate the proportional damping, calculation periods and frequencies. The time that I find myself using the nonlinear elements is dif...

how to make a rigid diaphragm in a frame 2d?

When I do the Eigen analysis, I have to use equaldof in direction 2 3?

Thanks vesna I think I have solved this problem, because I used the dof equal in the x direction. Now I want to ask you: I am doing a dynamic analysis of a reinforced concrete frame. When I calculate the period of my structure with elastic elements, I have a period of 0.54 s. when I calculate the pe...

I have made a dynamic analysis of a reinforced concrete frame and my analysis has failed. The error is: Arpacksolver: Error with saupd info= -9999 Could not build an Arnoldi factorization.

ok....
