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.

为了研究钢筋混凝土结构的抗震性能，进行了采用缩尺变形钢筋和微混凝土的钢筋混凝土小比例模型结构振动台试验。变形钢筋的公称直径为1、2和3 mm，其配置与日本工业标准中定义的配置成比例。“测试结构是1/15比例的十一层模型，每层有两个住宅单元。样本数量为2个，试验参数为平面形状。测试结果总结如下：1.模型结构的响应特性取决于刚度退化引起的基本周期的变化。最大反应幅值可由输入加速度的反应加速度谱来假定.在弹性阶段，层间剪力系数的分布近似于倒三角形分布。采用1/15缩尺模型试验，采用微混凝土和缩尺变形钢筋，可以有效地模拟结构的地震反应。
