Okay. Thank you

Dear Support Team,

I have noticed that using Lagrange multipliers slows the analysis down significantly. The analysis time is many times longer than the penalty function. Are there significant differences in the analysis results while using the two types of constraints?

By residual strength, I understand that upon reaching the performance criteria , the strength will be reduced to a specific percentage of the peak strength. I meant to ask if SeismoStruct has an option to input the particular percentage associated with residual strength. If not, what is the default ...

I have tried with the Residual Strength option. But most of the time, when I run using the 'Residual strength' or 'no strength' option, it results in the analysis failing to converge. Also, I would like to know what is the percentage associated with residual strength as couldn't find that ...

Thank you. To be sure if I understood you rightly, if I add a performance criterion for 'Core concrete crushing' in the columns, then any section of a column reaching that criterion can be considered as 'axial load failure' for that column. Hope this is what you meant?

Does Seismostruct have a mechanism to monitor axial failure in columns? I am looking to capture the gravity load failure typical of non ductile rc buildings.

Thank you for the prompt response. Also, as evident in the analysis log, several columns have reached core crushing and reinforcement fracture. Could this also be due to localisation issues associated with infrmFB elements? Are the infrmFBPH elements a preferred element class to model this class of ...

Hello Support Team,

I have been trying to Nonlinear Time History Analysis of a Three Story RC building. I have used InfrmFB elements for both beams and columns with 5 integration points. I have tried all the approaches to resolve convergence issues as mentioned in the manual as well as the ones ...

Hey, I have developed a model for a shear critical RC column using the inelastic force based element employing the mander model and menegotto pinto model. I have introduced a zero-length nonlinear link element using the Modified IMK model to simulate the shear degradation. I had attempted to find ...
