6. Reinforcement Requirement for Robustness The design of slab wall connections should not be made in isolation but should be as part of a structural system Ductility requirement of such a connection will depend on the robustness requirements of the structure of which it is part and the strategy chosen to achieve global robustness In the UK the Building Regulations for England and Wales for Scotland and for Northern Ireland all require buildings to be designed so in the event of an accident the structure will not suffer collapse to an extent disproportionate to the cause Similarly BS EN 1990 and BS EN 1991 1 7 describe the necessity for the design to take into account accidental situations whether identified or unspecified and to mitigate the associated risk Several possible strategies are proposed one of them is the provision of sufficient robustness for the structure by ensuring that structural members and materials have sufficient ductility and are capable of absorbing significant strain energy without rupture If such ductility at the wall slab connection is required if the wall thickness is more than the maximum recommended wall thickness i e the back of the anchor is not within the back of the wall reinforcement links are specified to provide a ductile connection The links are calculated to provide the same capacity as the main bars and are to be located above and below the top row of anchors 3 Glossary Glossary of terms used in th
