Effects of Cracks on the Seismic Analysis of Reinforced Concrete Nuclear Containment Vessels
This investigation studies the feasibility of the proposal for eliminating or reducing inclined steel in concrete containment vessels. The plausibility of this alternative design, which uses the combination of dowel action of the longitudinal reinforcement and the shear transfer capacity of the horizontal cracks, is studied. The results of tests performed to investigate the shear transfer characteristics of cracks are shown and discussed. The test results are used as input to a finite element model which is used to study the shear stress distribution of cracks. A computer program is developed which incorporates these experimental and analytical results into the seismic analysis of a cracked reinforced concrete containment vessel. A linear seismic analysis which yields results giving a least squares fit to the nonlinear results for the synthetic earthquake is also developed.
