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.

钢筋混凝土建筑倒塌的后果是严重的，无论是在成本上还是在生命安全方面。混凝土结构在受到地震、爆炸、意外撞击或其他过载等极端事件时，应发生过度变形，但不能倒塌，即必须是坚固耐用的。坚固性要求钢筋具有延展性，并充分锚固在混凝土中。当坍塌发生时，通常是由于钢筋锚固不充分。该项目将重新评估混凝土结构中钢筋的锚固要求，并为建筑业提供可靠的指导。该项目将直接提高结构的安全性和可靠性。
