Structural Retrofitting and Reinforcement

Studies of static reinforcement and strategic construction interventions

Anti-seismic technology has progressed in recent years, thus ensuring the construction of new buildings with high resistance to natural phenomena and always with the protection of human life in mind. However, much of the existing construction has been implemented in times when knowledge about earthquake-resistant technology was limited. As a result, a large percentage of these constructions do not meet the criteria for anti-seismic behavior and are vulnerable with the main pathology being the low resistance to seismic actions, the reduced stiffness or plasticity and the presence of a soft floor – pilot mechanism.

In addition, any interventions in existing buildings, such as floor additions, changes of use, geometry changes, etc., require the static control of the operator.

During the valuation study that precedes the reinforcement study, a conclusion is drawn about the behavior of the existing body in planning actions (earthquake, wind, snow, etc.). In the event that the operator’s behavior is deemed insufficient based on the applicable regulations and provisions, a static reinforcement study is prepared with the aim of restoring the operator and strengthening it for its safe operation.

The intervention strategies and the static reinforcement study are based on eurocode 8 and kan.epe.
