Abstract

A bonding-shear model of reinforced concrete shells and beams is presented that narrows the gap between flexural and full 3D continuum idealizations. Transverse shear strain provided by the Mindlin shell hypothesis is extended to form a consistent bending-shear strain and stress pattern. It works well up to ultimate failure of the cross-section. Hard missile impact results are compared to benchmark tests. An application to the safety assessment of a reactor containment against an aircraft impact is described. 1 Introduction Local impact effects on reinforced structures can be analyzed with fair accu- racy when general triaxial stress-strain state is considered and correspond- ing software utilized. There are several general purpose program packages including material laws suitable for concrete and reinforcement. S
