The experiment investigating that the loading direction exerts on ultimate shear strength of beam-column joint with different floor levels was carried out. The experiment was conducted on positive and negative alternating cyclic loading, and two specimens with different loading order were designed. The maximum negative load defined in this experiment was larger than the maximum positive load regardless of the loading order, and the maximum negative load for the specimen to which the negative load was conducted first was larger. The effect of the loading order made relatively less impact on the maximum load compared to the loading direction.
