The report contains a review of work on local bond transfer and the main factors which influence it, involving deformed reinforcing bar. Possible load transfer mechanisms are investigated and the significance of secondary cracking, local consolidation and shearing assessed. On the basis of these studies a linkage element, which realistically models bond action and is applicable to both monotonic and cyclic load, is proposed. Its ability accurately to predict stress, strain and crack geometry in typical reinforced concrete components is demonstrated by comparing the results of finite element analysis using this model, with experimental data. Aspects requiring further research are identified. An analysis of the dynamic response of a reinforced concrete beam is given which makes the simplifying assumption of rigid-plastic behaviour. A comparison of the analytical solution with experimental results obtained by bend tests in the Large Dynamic Test Facility at Ispra shows that, despite the neglect of elastic vibrations, a reasonable prediction of the fundamental response is obtained, providing due allowance is made for rate-of-strain effects.
