Abstract

Forced-Vibration tests were performed on two large-scale same models constructed on soft and hard ground in order to investigate the effect of the hardness and the stratification of the supporting ground on the vibration characteristics of simulated reactor buildings. The soft ground is almost stratification ground, and the hard ground is almost uniform ground. The test models are RC rigid frame structure with shear walls. In the tests, sinusoidal wave excitation was applied by the excitor. The vibration characteristics of the test models, earth pressure at the bottom of the base mat and the vibration characteristics of the surrounding ground were investigated. In the analysis, the soil impedances, the responses of the structure and the surrounding ground were almost simulated by Axisymmetric Finite Element Method.

Large-Scale Model Forced-Vibration Test Comparison of Test Results on Hard and Soft Ground

St. Louis, Missouri

Forced-Vibration tests were performed on two large-scale same models constructed on soft and hard ground in order to investigate the effect of the hardness and the stratification of the supporting ground on the vibration characteristics of simulated reactor buildings. The soft ground is almost stratification ground, and the hard ground is almost uniform ground. The test models are RC rigid frame structure with shear walls. In the tests, sinusoidal wave excitation was applied by the excitor. The vibration characteristics of the test models, earth pressure at the bottom of the base mat and the vibration characteristics of the surrounding ground were investigated. In the analysis, the soil impedances, the responses of the structure and the surrounding ground were almost simulated by Axisymmetric Finite Element Method.
