Nonlinear modeling of RC shear walls

Post by rezalatifi »

Dear,

For nonlinear modeling of RC shear walls, shell elements or column elements with a fiber cross-section have been used in SeismoBuild? For more information, please provide me some references or papers regarding using an equivalent nonlinear 1D element instead of shell elements.

Sincerely

Dear rezalatifi,

As it is written in SeismoBuild's User Manual: In SeismoBuild, use is made of the so-called fibre approach to represent the cross-section behaviour, where each fibre is associated with a uniaxial stress-strain relationship; the sectional stress-strain state of beam-column elements is then obtained through the integration of the nonlinear uniaxial stress-strain response of the individual fibres in which the section has been subdivided.
