Abstract: The analytical method of estimation of frame construction life prediction in terms of creep by strain failure criterion is suggested. The linearization of stochastic rheological energy equations, is made, the estimations of uptime under the assumptions on the limit values of creep are obtained. The checking of accordance of the method with the experimental data for the creep of samples made of 12Kh18N10T steel under $T=850\ ^\circ C$ is implemented. There is agreement between the calculated and experimental data.

Keywords: creep, stress-rupture strength, stochastic model, probability of no-failure, strain failure criterion.
