METHODS FOR RANDOM THERMAL CREEP STRESS ANALYSIS OF MASSIVE CONCRETE STRUCTURES

Stochastic finite element method for random the rmal creep stress inmassive concrete structures is presented. In the proposed method, various kinds of random factors including material physical parameters and random temperature in concrete are taken into account. Owing to the effect of stochastic environmental temperature, hydration heat of concrete and random heat conductivity parameters, the temperature in concrete appears to be non-stationary process. Based on the linear creep law, the effect of temperat...
