Some of the strategies to reduce the risk of accidental action include preventing or reducing action from occurring, protecting the building from the effects of the action or ensuring that the building can still function after the action. Several approaches can be taken to ensure that the building can survive the action. By including sufficient redundancy in the structure, alternative load paths can take the load if a bearing member is destroyed. Another approach is to provide satisfactory ductility in members to be able to absorb the energy from impact without leading to failure. The final way is to design key elements to be able to withstand the accidental impact and only allow nonbearing members to be eliminated.
