Abstract

TWO FULL-SCALE CORNER BEAM-COLUMN SPECIMENS WITH AND WITHOUT FUSE BARS WERE DESIGNED, CONSTRUCTED, TESTED, ANALYSIS AND MODELED UNDER IN-PLANE LATERAL CYCLIC LOADING PRESENTED HEREIN. THE FIRST SPECIMEN WAS DESIGNED USING EUROCODE 8 AND EQUIPPED WITH FOUR NUMBERS OF FUSE BARS INSIDE THE JOINT AND THE SECOND SPECIMEN WAS DESIGNED USING BS8110 (NON-SEISMIC CODE OF PRACTICE) WITH CORBEL. ALL THE SPECIMENS CONSIST HAVE SIMILAR FOUNDATION BEAM, COLUMNS AND BEAMS. VISUAL OBSERVATION DURING EXPERIMENT SHOWED THAT CORNER JOINT WITH FUSE BARS SUFFERED LESS DAMAGE AS COMPARE WITH JOINT WITHOUT FUSE BARS. IN ADDITION, EXPERIMENTAL RESULTS ALSO SHOWS THAT CORNER JOINT WITH FUSE BARS HAS HIGHER LATERAL STRENGTH CAPACITY, STIFFNESS, DUCTILITY AND EQUIVALENT VISCOUS DAMPING THAN CORNER JOINT WITHOUT FUSE BARS. FURTHERMORE, THERE IS SIMILARITY OF HYSTERESIS LOOPS BETWEEN EXPERIMENT AND MODELING USING MODEL OF PAMPANIN FROM RUAUMOKO 2D PROGRAM. FINALLY, THERE IS GOOD AGREEMENT OF LATERAL STRENGTH CAPACITY, DUCTILITY, STIFFNESS AND EQUIVALENT VISCOUS DAMPING WHICH LIES BETWEEN 2% AND 20% BETWEEN EXPERIMENT AND MODELING HYSTERESIS LOOPS. THEREFORE, IT CAN BE CONCLUDED THAT THE CORNER BEAM-COLUMN JOINT WITH FUSE BARS PERFORMED BETTER THAN CORNER BEAM-COLUMN JOINT WITHOUT FUSE BARS. THUS, IT IS RECOMMENDED THAT FUSE BARS AS GREEN STRUCTURAL MATERIALS CAN BE INSTALLED INSIDE THE CORNER BEAM-COLUMN JOINT FOR RC BUILDINGS TO CATER FOR MODERATE TO STRONG EARTHQUAKE IN HIGH SEISMIC REGIONS.
