The present study deals with the Finite Element Analysis (FEA) of masonry structures by means of Bott-Duffin inverse. There are various kinds of structural problem about static and dynamic behaviors under the subsidiary condition of displacement such as contact problem, unilateral stress problem, homology design problem, etc. In masonry structures, due to the material properties, only compressive stress is assumed to exist and to a certain extent they become contact problem. Bott·Duffin inverse enables us to present an automatic analytical method for a system of simultaneous linear equations with the subsidiary condition of unknowns. In this paper, Bott·Duffin inverse is briefly introduced and its application to static and dynamic contact analyses of masonry structures are presented.
