The main objective of this study is to examine the behaviour of two-stories one-bay steel frames with Y-shaped brace subjected to a severe earthquake by the "On-line computer test control method". This on-line test has been carried out to demonstrate the good earthquake-resistant capacities of this type of structural design. Emphasis has been put on the capacity of the structure to sustain large deflections and to dissipate substantial energy in its inelastic range. Besides, the determination of the dynamic response of the structure has been achieved. On the other hand, an earthquake response analysis of its hysteretic behaviour using the Ramberg-Osgood model for steel structures has been performed. The correlation between experimental and analytical results has been studied.
