The purpose of this report is to clarify the dynamical characteristics of the soil ground subjected to earhtquake excitation, and to evaluate quantitatively the input energy to a frame by the ground motion accounting the effects of the surrounding soils.Respones analysis of a test model by a computer-actuator on-line system and the following vibration generator tests were caaried out.1. The vibration test of a footing by the vibrator installed on the surfacs footing.2. The vibration test of a test model with the footing by the vibrator installed on the surface footing.3. The vibration test of a footing by the vibrator installed on the embedded footing.4. The vibration test of a test model with the footing by the vibrator installed on the embedded footing.The test results were compared with the theoritical results. Finally, a new method to estimate the effective input energy to a frame accounting the effects of the internal damping and the radiation damping of the ground was presented.

该报告的目的是阐明受到兴奋的土壤地面的动态特征，并通过地面运动来定量评估输入能量到框架，从而计算周围土壤的影响。通过一个测试模型分析测试模型计算机传动机在线系统和以下振动发生器测试被浮出水1。振动器安装在表面上的振动器的振动测试2。测试模型的振动测试，其振动器安装在表面基础上。3。安装在嵌入式立场上的振动器的基础的振动测试4。测试模型的振动测试与安装在嵌入式基础上的振动器的基础。测试结果与理论上的结果进行了比较。最后，提出了一种新的方法，以估算有效输入能量的框架，以说明内部阻尼的影响和地面的辐射阻尼的效果。
