Students in Lisbon study the design of an earthquake-resistant building.

The need to emphasize the strengthening of buildings against seismic impacts is gaining more and more attention, especially in Lisbon, where the risk of natural disasters of this kind is considered higher by the scientific community. Prevention is becoming an important word.

With this concern in mind, the construction company Level Constellation (LC), which has been present in Portugal for several years, organized a visit to a construction site in the capital, the CITIFLAT Avenidas Novas project, which is already ready to test the effects of a possible earthquake. About 40 students visited the construction site, who believe they are now better prepared to deal with issues related to the seismic resistance of buildings.

CITIFLAT Avenidas Novas,'''located on Elias Garcia Street, hosted a group of 40 students and teachers from the Professional Technical Course in Construction on October 18.

The property in question is an old office building built in the early 1970s, licensed in 2022 to be turned into a luxury residential complex with 17 apartments. The existing building, with the exception of some local areas with openings in the floor slabs and extensions to the rear of the floors, will generally be''preserved, the construction company reports, noting that the quality and durability of its original concrete structure has become highly questionable due to aging in recent decades. Consequently, any reconstruction without analyzing and strengthening the structure will result in an increased potential for seismic risk.

The construction company, A2P, responsible for the structural engineering design, decided to implement an important renovation for the stability and safety of this building, which includes the following approaches:

• Mixed structure of reinforced concrete and metal reinforcements
• Concrete reinforcements with projection
• Prestressing of beams
• New concrete reinforcements''
