Manufacturing Technique and Material Properties for 1/5-Scale Reinforced Concrete Frame Model

This study presents the techniques to manufacture the model concrete and model reinforcement for the 1/5-scale 3-story reinforced concrete frame. The used model concrete has sufficient workability but shows a little lower strength than expected model steel was made of commercial $\phi$3.2mm and $\phi$2.0mm wire by using deforming device and vacuum tube electric furnace. The yield strength can be simulated but it was difficult to simulate the other properties. The load cell was specially manufactured to measure the shear force in the columns of the first story. The carrying frame and the hinge adapter of artificial mass are explained. The special problems in the process of construction of model are also dressed.
