【 摘 要 】

The ability of the beam to receive a seismic load can be explained in the experimental study of a castellated beam using RBS (reduced beam section) as a damping factor on earthquake resistant building structure. Evaluation of the structure of the exterior connections was done by subjecting cyclic loads gradually until collapsed to evaluate castellated beam test specimens with and without RBS. The experimental test conducted by cyclic test aimed to determine the ability of deformation and the force that worked due to the influence of RBS placement from the column face on the castellated beam. Investment of RBS positions on the columns in the column face shows that failures occurred due to the bending on the shaft. The results obtained by each load to the drift ratio were as follows. On the test specimens with RBS, the melting point was at 8 kN loading with a 1.05% drift ratio, 2.1% drift load at a 9 kN load, 3.20% drift at a peak load of 12 kN, and necking phase at 10.53 kN load with 4.17% drift.
