Abstract

Various scenarios may entail the need for the retrofit of an existing structure, which will be exposed to a variety of loading conditions and degrading environmental actions during its life time. In most cases, the objective of structural strengthening will be to reduce the risk of loss of life, whilst recognizing the importance of buildings and monuments to our societies’ heritage. However, the general criterion that should guide any decision related to structural strengthening should be to optimize the resources to be invested compared with the benefits to be obtained. In this chapter a range of important motives, concepts and approaches for strengthening and retrofitting are introduced. The various phases of a modern seismic assessment are described, since earthquakes have been seen to cost society dearly around the world. However, it is also explained that similar assessment and retrofit considerations and procedures are applicable for other hazards too. It is demonstrated that a variety of interventions will be possible and means of gauging their impact on response is conceptually explained. Later chapters in this book will build on this introduction to provide the detail required to finalise a retrofit design.
