Presents some methods for predicting and accounting for the changes in stress when designing a structure with materials that are known to creep, such as concrete, polymers, and wood. The calculations are complex because most structures are heterogenous and different materials will creep different directions at different speeds and with different effects. Among the aspects considered are fundamental equations, reinforcing elements by the operator method, solving problems in the theory of inherent elasticity, initial and boundary value problems, and optimal design. An appendix contains the code for a program in FORTRAN for approximating functions of the Volterra operator. Revised and translated from Raschet stroitel'nick konstructsii uchetom polzuchesti published by Stroizdat, Moscow, in 1988. No index. Annotation c. by Book News, Inc., Portland, Or.

A translation of "Raschet Stroitel 'Nikh Konstruktsii Uchetom Polzuchesti", published in Moscow in 1988. This is a presentation of the general principles and methods of design of continuous solid bodies and elemental reinforcement systems in materials which possess creep and ageing properties.
