VALUE-ADDED 5-STORY STEEL FRAME AND ITS COMPONENTS:PART 2 - FULL-SCALE TESTS OF BEAM-COLUMN-GUSSET PLATE ASSEMBLIES
This paper discusses the full-size experiment of beam-column-gusset plate assemblies. High strength and high ductility are required so that the passively-controlled structure demonstrate an enough performance under a severe earthquake. However, the behavior of those assemblies has not been clarified satisfactorily and further improvement of the design method is expected. A new loading method in which a hydraulic jack is applied as a virtual damper is developed and the case of steel damper is mainly discussed. Also dampers with velocity sensitivity, such as viscoelastic damper can be tested under static condition by this method. A frame with typical members of the 5-story steel building is set as a standard specimen, and inter story drift is increased from 1/800 to 1/33. Two cycles are applied in each loading cycle. Furthermore, fatigue tests are conducted under the story drift of 1/50 or 1/33. Consequently, the effect of the presence of the gusset plate, stiffeners,and damper force on failure mode, cumulated deformation capacity, hysteretic behavior, and distribution of strain is discussed.
