An Experimental Study on the Materials for Small-Scale Models of Structures |
| Abstract |
Three types of model concrete with different mix ratios for 1/10 scale reinforced concrete model were made and tested to find the best solution for the simulation of mechanical characteristics of prototype concrete. Scaled reinforcing materials in diameter(D1.8) having similar configuration and mechanical properties with commercial deformed bars (D19) were prepared for 1/10 scale model tests of reinforced concrete structures.Two types of model test using D1.8 model reinforcing bars and model concrete, monotonic simple beam test and cyclic cantilever beam test, were performed to ensure and check the similitude of bond behavior between 1/10 scale model and prototype. The test results showed that the flexural behavior of 1/10 scale models can be simulated with accuracy enough for practical use in monotonic and cyclic loading test.The 1/10 scale models for steel beam-column connections which have two types, flexible and rigid, were manufactured and tested under cyclic loading. The test results of these models for hysteretic behavior were compared with those of prototype (1/2 scale). From this comparison, it was found that 1/10 scale steel structure model can be used to predict the behavior of prototype structure with a high level of reliability. |
