Intervention procedures to upgrade existing ordinary structures which are designed and executed according to older codes


Scope of the Entry

This entry presents basic principles, criteria, and procedures in regard to the conceptual design of seismic strengthening of existing ordinary structures and its treatment in current codes. In this context, certain code provisions constitute a significant part of the present entry.

Although it can be read by nonexperts, this entry is mainly addressed to structural engineers involved in the design of structures and interventions in buildings.

Notes on Terminology Used

The terms used in the entry are standard and familiar to engineers; nevertheless some clarifications are in order:
  • Seismic: The entry is restricted to seismic upgrading only. Certain aspects of the methodology may also apply to upgrading against other actions. However, it is pointed out that the main characteristic of a seismic strengthening strategy is the fact...
