TORSIONAL RADIATION DAMPING OF ARBITRARILY SHAPED EMBEDDED FOUNDATIONS

This is the second of two papers on the dynamic response of arbitrarily shaped rigid foundations embedded in elastic half-space and subjected to a harmonic torsional excitation. This paper presents information for computing the radiation dashpot coefficient which represents the geometric spreading of elastic energy by waves propagating away from the foundation. The numerical results in this paper obtained with a rigorous boundary element algorithm outlined in the first paper are presented in the form of dimensionless graphs for the dashpot coefficients, covering a wide range of basemat shapes, embedment depths, and frequencies of excitation.
