Pushover analysis-material sets

Post by leartt »

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 section where I define the constituent materials as new materials, should I modify the compressive strength of the concrete to 25 MPa and the yield strength of the steel to 500 MPa, instead of using the default mean strength values?
Kind regards

According to all modern codes on Structural Assessment, the nonlinear analysis are conducted considering the mean, rather than the characteristic material values.
