Finite elements of the structure are derived by using beam schemes including Timoshenko type beam. The finite elements descriptions are completed by plate state. The way of elements connections and the global system of equations are also defined. The finite elements of wall panels, floor slabs, joints ant contact type subsoilproposed in this study significantly reduce the number of unknowns. Two computational examples proved the efficiency and the computing possibilities of the presented model. http://pubs.sciepub.com/ajcea/2/4/4/ajcea-2-4-4.pdf building structure modelling set of finite elements beam elements soil-structure interaction finite element method
