Introduction
QUAKE/W is designed and implemented primarily for analyzing the effects of earthquakes on earth structures. The same implementation can also be used to investigate the effect of a sudden impact on the structure, such as controlled blasting in an open pit mine. In a finite element stress-strain formulation, the activating forces can come as: (1) a body load, like an earthquake, (2) a specified nodal boundary force, or (3) specified nodal displacements. Velocities and accelerations cannot be applied as boundary conditions; at least not directly. Acceleration or velocity variations with time can, however, be integrated and applied as displacements with time at any particular location. This example illustrates how this can be done. A velocity versus time record for an imaginary blast at the foot of a slope is converted into a displacement versus time function, and then applied as a boundary condition.
