RESPONSE OF TORSIONALLY EXCITED FOUNDATIONS

A study was made of two aspects of the response of a rigid, massless foundation of a circular plan, which is supported at the surface of a homogeneous, elastic half space and is excited by a torque about an axis normal to the foundation. A simple discrete model characterized by frequency-independent parameters, is presented. In addition, closed form expressions have been presented for the impulse response functions of the system. The response functions considered include the rotation associated with a unit impulsive torgue, and the torque associated with a unit implusive rotation. With the aid of these functions, the response of the system to an arbitrary excitation and the force associated with a prescribed response may be evaluated by direct integration in the time domain.
