Abstract

This paper presents a new method for the analysis of plates in bending with internal constraints. The proposed method can be regarded as an extension of the well-known force method in matrix analysis of structures. The proposed solution is performed through two phases: the released plate phase, in which the plate is released from all internal constraints and solved using the Boundary Element Method (BEM). The effect of internal constraints is considered in the second phase, where a series of the unit virtual loads is placed instead of the unknown redundant reactions at internal constraints. The flexibility matrix is formed by satisfying the compatibility of deformations at the internal locations of supports. Hence the corresponding system of equations is solved
