Popis: A full scale 3-story 3-bay concrete filled steel tube (CFT) column and buckling restrained braced (BRB) composite frame was tested using pseudo dynamic testing procedures and four earthquake accelerations. The key features of the structural system include using three different types of beam-to-CFT column moment connections as well as three different types of BRB . The CFT/BRB frame was designed using the displacement based seismic design procedure with a target inter-story drift limits of 0.02 and 0.025 radians for two hazard levels, 10% and 2% chances of exceedance in 50 years, respecti vely. The pseudo dynamic and analytical predicted responses of the specimen observed during the application of the earthquake load effects are in good agreement. This experimental program illustrates that the experimental response data and the video images of the specimen can be effectively disseminated through the Internet during and after the test s.
