Abstract

Numerical analyses are carried out by using the ABAQUS finite element program to predict the ultimate pressure capacity and the failure mode of the BWR Mark III reinforced concrete containment strengthened by composite materials or steel plates at various positions. Material non-linear behaviour for concrete, steel, and fibre composite laminate material are all simulated with proper constitutive models. It has been shown that the use of [±θ/90/0] ss composite materials with 50 ≤ θ ≤ 90° to strengthen the containnment at the upper cylinder and the dome achieves the most satisfactory strengthening results. (The fibre angle of the lamina is measured counter-clockwise through the outward normal direction from the meridian of the containment shell structure.)
