Realization of reinforced concrete structures analysis with the account of physical and geometrical nonlinearity in computer program PRINS

An algorithm of physically and geometrically nonlinear static analysis of structures by the finite element method is described, the distinguishing feature of which is the use of a full nonlinear stiffness matrix. This matrix is represented as the sum of five terms, namely, the stiffness matrix of th...
