Abstract
The method developed to analyze the stress and deflection of plates on unilateral foundation is different from the traditional method. The behavior of plates on unilateral foundation belongs to that of free-boundary problems. It has been proved effective to solve the problems of free-boundary using the linear complementary equation method. In this paper, a boundary element–linear complementary equation is derived according to contact theory. This equation is used to analyze plate-bending on elastic half-space foundation, especially considering the impact on the internal force and displacement of plate, which is caused by the neighboring loads acting on the foundation around the plate. The effectiveness of the method is illustrated by numerical results.
