In recent decades, the use of High Performance Concrete (HPC) has grown vastly, being used in multiple applications with high requirements. However, the use of recycled aggregates (RA) has been mostly limited to conventional ...

The use of structural fibre as replacement of the traditional reinforcement in precast concrete segmental linings is a widespread practice. As a matter of fact, more than forty examples of application in tunnels and vertical ...

Se desarrolla una herramienta de cálculo para asistir al proyecto de estructuras continuas de hormigón pretensado, ya sean de tipo viga continua o pórticos. La misma es aplicable a entornos docentes para la enseñanza ...

Se presenta la investigación teórica y experimental realizada por los autores durante los últimos años en colaboración con empresas de prefabricación y de aerogeneradores, que ha dado lugar a nuevos tipos estructurales ...

Carbon steel reinforcement is vulnerable to corrosion, degrading the structure with time, and has large economic implications for aging infrastructures. CFRP is an alternative in reinforced and prestressed concrete, not ...

Nowadays, several tunnels bored with Tunnel Boring Machines (TBM) are already in service and various dozens are being constructed around the world. The internal support of these usually consist of precast concrete segmental ...

Prestressing tendons made of fiber-reinforced polymers (FRPs) are a promising alternative to conventional steel tendons in prestressed concrete structures owing to their corrosion resistance. However, the shear strength ...
