- Abstract
This paper provides a program to adopt based on modeling the nonlinear behavior of arbitrary elements with combination of material nonlinearity and geometric nonlinearity for the purpose of structures assessment. In this study, total Lagrangian formulation is developed based on separate fibers with uniaxial behavior and interface elements with shear response of local stress field models, simultaneously. The accuracy of the suggested approach is verified through comparison of experimental results and existing analytical methods.
