CRITERIA FOR THE INITIATION OF MODES OF RESPONSE OF A CAISSON SUBJECTED TO A BREAKING WAVE FORCE
This paper concerns problems of a caisson subjected to a breaking wave force: (1) what are the possible modes of response and (2) the conditions initiate into these modes. These two questions have not been studied. The objective of this paper is to answer these two questions. However, the actual response of a caisson that takes place in each mode is not addressed in this study. A caisson placed on a horizontal frictional base, subjected to a concentrated horizontal force of short duration, applied to the seaward side face of the caisson and accompanied by a corresponding uplift force on the bottom of the caisson, is modeled as a free-standing rigid body. The conditions for the initiation of each mode of motion are derived using the equations of motion of a plane rigid body. The results are given in explicit analytical form and presented graphically. Knowing the magnitude and location of the force, coefficient of friction and the aspect ratio of the body, the mode of motion may be identified easily from the graphs.
