Greetings,
I have a question regarding the Mander concrete model. How is the peak stress in compression for the confined concrete calculated in SeismoStruct? I conducted a comparatory analysis of a RC column with an incrementally increasing vertical load (in compression) and the result of the peak ...

Greetings,
I have a question regarding the expected yield strength of reinforcing steel that is calculated by default by SeismoStruct. Being fully aware that it can be changed by the user, is there any specific reason why the factor is 1.15? Paulay and Priestley recommend the value of 1.1 for ...

Thank you for the reply. Any tips on how to overcome these issues in this model?
Kind regards

Thank you for the information. So to sum it up, because of this bug, the analysis is not fully conducted using the DBPH nonlinear modelling approach? I was wondering this, since I conducted static time-history analysis of the same one-bay RC frame, with the same dynamic lateral load, and with all ...

After I define the material models for concrete (Mander et al. nonlinear c.m.) and for reinforcing steel (Menegotto-Pinto), the RC sections of the bare frame elements and the Beam-Column element types with the help of displacement-based plastic hinge approach, I double click for example the beam of ...

Hello,
in the process of modelling a one-bay RC frame, by using the DBPH nonlinear modelling approach, there is an error message that states: the automatic calculation of the hinge properties is not supported for the selected section type. The section types are regular squared and rectangular RC ...

Greetings,
Let's say I want to conduct some kind of nonlinear analysis, for example a pushover analysis on a hypothetical RC frame, where my only output of interest is the pushover curve (and not conducting the code-based checks). Let's say the constituent materials are C20/25 and S500. In the ...

Greetings
I tried making the convergence criteria more stringent, in line with the steps that are shown in your video tutorials, but to no avail. The problem still exists. I would really appreciate it if there is a possibility of me sending the .spf file so that you can check out the issue.
Kind ...

The weird thing is that in some cases when I apply a scale factor of, for example 3.21, the analysis is conducted without an issue. However when I apply a scale factor of 3.2, the analysis is terminated after a certain time step.
