Abstract


The design of the concrete structure, the tensile stress that occurs is held by reinforcing  steel, while the tensile concrete is not calculated to withstand the tensile stresses that occur because the concrete will soon crack if it gets tensile stress that exceeds the tensile strength. Earthquake is one of the major problems facing Indonesia. should have sufficient strength and ductility to be able to accommodate earthquakes that occur. The purpose of this study was to analyze the ductality value of column beam relationships in the joints due to cyclic loads. The method used in this study is an experimental study method. For the length of the coupling beam the same is maintained for the whole coupling beam of 115 cm so that the beam height is calculated based on the length and the ratio of length to height, 40 cm for each specimen. The results of the study showed that the normal coupling beam component had a ductility of 3.86 while the coupling beam component which had fiber with a 40 cm joint length had a ductality value of 4.01. It was concluded that the structural performance levels of both normal and fiber coupling beam components with a length and height of 40 cm and 40 cm coupling beam models based on SNI - 1726 -  2002 were at the level of partial ductality
