Study of Deformation of Structural Elements as Result of Concrete Creep

The paper considers the basic principles of the linear theory of inherent creep and the possibility of its application to the calculation of shell structures made of concrete. A mathematical model of the deformation of the structure under consideration is shown in the form of a functional of the total strain potential energy. An algorithm based on the Ritz method is applied. The stability calculations of shallow shells of double curvature and square in plan are made, taking into account the creep of the material. The critical time values are found for different values of the applied load.
