Abstract EN
A simple model for vertical dynamic interactions among a group of strip footings rested on half-space is presented in this paper.
An analytical method is presented to obtain the contact pressures and the impedance matrix for a group of surface strip footings.
In order to conveniently solve the unknown contact pressures between the soil and footings, the soil-footing interfaces are discretized into a series of strip elements.
The Green function for each element under uniform harmonic force is derived and calculated by the piecewise integration and Cauchy principal value integral.
The influences of footing and soil parameters on contact pressures and vertical dynamic impedances of footing groups are discussed in detail.
The SSSI effect between adjacent footings increases with the decrease of the distance ratio S/L.
For three footings in a group, the middle footing experiences greater cross-interactional effect than the side ones.
The present method has high accuracy, which is not only simple but also suitable for the high-frequency analysis.
