hermal creep stresses in mass concrete structures are influenced by many random factors including the random temperature in the concrete.

Stochastic finite element method for random the rmal creep stress inmassive concrete structures is presented.

In creep stress analysis of concrete structures during construction period , the necessity to as-semble and decompose a large stiffness matrix for each time increment makes the computation verylengthy.

A whole process simulation calculation is done for the temperature field and creep thermal stress field of Baise RCC gravity dam from construction stage to operation stage under summer shutdown scheme by using 3D FEM relocating mesh method.

Concentrated on the questions in heightening of dams, and focused on the practice of heightening of Danjiangkou dam, questions in heightening of concrete gravity dams were systematically studied such as connection of new and old concrete, temperature field, and thermal creep stress field by using of large F.

But temperature field and thermal creep stress of the roller comp.

The measured strain of concrete includes the elastic strain,creep strain and also the non-stress strain like the concrete free deformation and temperature strain.
