RESUMO

The stochastic finite differences technique is used for the analysis of pore pressure in a concrete structure with random material properties subjected to fire loading. The problem is described theoretically with assumption of random liquid contents. A system of partial differential equations is solved for the first two probabilistic moments of the random pressure field. An example of stochastic analysis in concrete structure with random liquid content is given.
