Influence matrix of superelement model of a straight rod with cross-sectional rends on dynamic state of elastic and linear and viscoelastic bodies
The paper considers problems of creation of calculations system on the basis of finite element method. «One rod-one finite element» principle is put in a system base. Analytical solutions of statics and dynamics problems of an elastic and linear and viscoelastic straight rod are used for an admitted method unlike tradition approach which consists in assignment of polynomial shape functions to a finite element. The rod has specific typical shape of the finite element for the admitted method. The paper presents a way of creation of a superelement of the straight rod which can be applied for an analysis of states of buildings frameworks.
