Performance based assessment of steel frame structures by different material models

Acceptable limit conditions for materials used in structures are one of the influential factors for design and evaluation of buildings. These limits are described using different material models. Material models can be generally defined by the stressstrain relationship. Stress-strain relationship varies based on the material. Mathematical models are used for describing the stress-strain relationship for any material. The material model takes a very important role in the seismic analysis of structures. The aim of this study is investigate of effects of steel models on structural performance of steel frame buildings. For this aim, pushover curves were obtained for three different steel models. It was determined that the pushover curves obtained according to three various steel models used in the study were consonant with each other.
