Best way to model different materials

Post by aldrich_mayoralgo »

Hello! :)

I am a Civil Engineering Student currently working on my thesis which is related to generating fragility curves for Gabaldon type school buildings here in the Philippines.

I was in the process of modelling when I wondered what is the best way to model different materials? Some of the schools that I am modelling might have wooden members. Some might be made purely of reinforced concrete.

I have the following question:
1) Is wood material best modelled as el_mat, hyst_mat, or best modelled in some other way?

Thank you for your help. :)

It depends on whether you want to model material inelasticity. If not (e.g. if you assume linear behaviour of the wooden beams and you concentrate inelasticity at the joints) the el_mat should be enough. If however you need to model the member inelasticity, then the hyst_mat material with appropriate parameters is suitable.
