| Research Abstract |
Shaking table tests of small scaled reinforced concrete model structures using scaled deformed reinforcing bars and micro concrete were conducted to investigate the seismic behavior of reinforced concrete structures. Nominal 'diameters of the deformed reinforcing bars were 1, 2 and 3mm, which configuration was proportional to that defined in the Japan Industrial standard. 'The test structures were 1/15 scaled eleven-storied models with two dwelling units at each story. The number of specimens was two with the test parameter of the shape of the plan. The test results are summarized as follows ;
1. Response characteristics of model structures depended upon changes of fundamental period due to stiffness deterioration. The maximum response amplitude could be assumed from response acceleration spectrum of input acceleration.
2. The distribution of story shear force coefficients was similar to inverted triangular force distribution at elastic stage. The inverted triangular force distribution, however, underestimates the distribution of story shear force coefficients at upper stories in plastic stage.
Shaking table tests of 1/15 scaled model structure used micro concrete and scaled deformed reinforcing bars are effective enough to simulate the earthquake response.
