【 摘 要 】

The paper discusses a multi-factor experiment method for determining the strength and stiffness of flanged beam-to-column connections. The method suggests two identical models - full-scale and numerical development. Models are matched by geometry and initial imperfections, physical properties of materials, boundary conditions and full loading history. They are matched by displacement and deformation at each loading stage of the models. When the results match, the conducted experiments can be stated and obtained mathematical models are correct and valid, hence using expensive full-scale models in further research can be avoided.
