Hi everyone
I am modeling a 5 story X-brace system but its pushover analysis doesn't converge.
Can someone give me the required code?
I have attached the model here:

Thanks

Hi everyone I am trying to model a one-story steel frame with diagonal CBF bracing. I want to simulate a hinge located in the middle of the brace, according to the multi-linear backbone curve introduced in the ASCE 41-13 with corresponding parameters stated in Table 9-7. How can I model this behavio...

Hi I want to model an equivalent SDOF with Bilin material. My original structure is steel frame. I want to consider the cyclic deterioration parameter (Lamda) for the SDOF model. Is there any relation or approximate value for this aim? For equivalent SDOF of concrete frames, Dolsek presented a appro...

I want to model an Ibarra-Krawinkler hysteretic material for an infill compressive strut with these parameters: Fy_strut , delta_y_strut Fc_strut , delta_c_strut Fr_strut , delta_r_strut k_f_strut , k_d_strut (Pinching parameters corresponding to stress and strain) According to this picture: http://...

Thank you for the solution . The problem was solved

According to bellow picture, I want to model an Ibarra-Krawinkler hysteretic material for an infill compressive strut: http://uupload.ir/files/jqr8_strut_matrial.jpg When I used "uniaxialMaterial Hysteretic" material, this error apeared: "HystereticMaterial::HystereticMaterial -- inpu...
