Plastic behaviour of deformable reinforced concrete box sections under eccentric load

TL;DRAbstract

This thesis deals with the plastic behaviour of deformable reinforced concrete box sections under eccentric load. Analytical, numerical and experimental studies of this topic has been carried out.An elasto-plastic finite element model for reinforced concrete plates/panels and shells has been developed. The model is based on yield functions derived from the rigid-plastic yield line theory. A stress resultant finite element model of reinforced concrete shells has not previously been reported in the literature.The developed finite element model has been used to evaluate the plastic behaviour of deformable box sections under eccentric load. This investigation has shown that when a box section is exposed to eccentric load, plasticity will spread along the box, and that the spread of plasticity is primarily associated with the development of plastic comer hinges. Based on a comprehensive parametric investigation, which involved variation in geometry and material strength of a box section, it
