Anchorage of reinforcement in concrete structures subjected to loading and environmental extremes

The consequences of collapse of a reinforced concrete building are severe both in terms of cost and human lives. When subjected to extreme events, such as earthquake, blast, accidental impact or other overloads, a concrete structure should deform excessively, but not collapse, i.e. it must be robust. Robustness requires that the steel reinforcement is ductile and that it is adequately anchored in the concrete. When a collapse does occur, it is often due to inadequate anchorage of the steel bars. This project will re-assess the anchorage requirements for reinforcement in concrete structures and provide reliable guidance to the construction industry. The project will lead directly to improvements in the safety and reliability of structures.
