Vertical Displacement Analysis of Embedded Square Foundation Under Vertical Dynamic Load
The aim of this research is to study the effect of embedment depth of square foundation subjected to dynamic machine loading on the resonance displacement of foundation. In order to validate the current theoretical method, a comparison with the experimental investigation was conducted regarding the vertical displacement. The foundation embedment depth ratio, which is defined as a ratio of embedment depth to the total depth of foundation, was taken as (0, 25, 50, 75, 100) %. The foundation embedment depth ratio affected the resonance displacement of the foundation due to changing both dynamic coefficients of damping and stiffness while applying dynamic machine loads. In addition to the embedment depth ratio of the foundation, the effect of both of dimension of square foundation (2B) and dimensionless frequency (ao) on the resonance frequency was investigated. Results showed a high level of convergence between the current theoretical method with the experimental investigation regarding vertical displacement. The difference of vertical displacement results between the two methods ranged between (7 × 10–4 to 5 × 10–3) mm. It was also concluded that the resonance frequency decreases with the percentage increment of foundation embedment and dimension of square foundation and with a decrement of the dimensionless frequency (ao).
