| Steel and stainless-steel girders are widely used around the world. However, relying solely on experimental testing of these girders is not always ideal since numerical simulations can also be utilized. Although experimental tests provide accurate results, numerical simulations offer several potential advantages. For example, they require fewer resources, including human, financial, and material resources. Moreover, numerical simulations can be applied to a broader range of structural parameters and loading conditions. Nonetheless, it is crucial to conduct a verification study before carrying out any numerical simulations to ensure that the developed numerical model accurately captures the actual behavior of the girder. Consequently, this research aims to verify the accuracy of finite element models of girders created in Ansys Workbench (2020 R1) by comparing them to experimental results from previously tested girders found in literature. The verification study uses models of specimens from different sources, including specimens made of stainless-steel, specimens with hollow tubular flanges, and stainless-steel girders with diagonal stiffeners. It is found that the finite element model can predict the ultimate strength and elastic stiffness of the girders with an average error of less than 3 and 0.4% respectively. Additionally, the model is able to simulate the deformed shape of the girders at the failure stage. Overall, the study demonstrated that the finite element model is effective at predicting the response of girders with different characteristics. | ||||
