COMPORTAMIENTO ADHERENTE DIFERIDO DE ARMADURAS PRETESAS EN HORMIGÓN

Caro Forero, Libardo Andrés (Universitat Politècnica de València, 2012-07-23)

El comportamiento de los elementos estructurales de hormigón depende considerablemente de la adherencia armadura-hormigón. En elementos de hormigón pretensado mediante armaduras pretesas, el hormigonado se realiza alrededor ...
Experimental Technique for Measuring the Long-term Transfer Length in Prestressed Concrete

Martí Vargas, José Rocío; Caro Forero, Libardo Andrés; Serna Ros, Pedro (Wiley: 12 months, 2013-04)

This article presents a proposal of a test set-up and methodology for testing the transfer length evolution through time of prestressing reinforcement in pretensioned prestressed concrete members, aimed at providing a basis ...
Measuring specific parameters in pretensioned concrete members using a single testing technique

Martí Vargas, José Rocío; García Taengua, Emilio José; Caro Forero, Libardo Andrés; Serna Ros, Pedro (Elsevier, 2014-03)

Pretensioned concrete members are designed and manufactured by using at least two materials: concrete and prestressing reinforcement. Also, two main stages must be considered: prestress transfer and member loading. Hence, ...
Prestress losses evaluation in prestressed concrete prismatic specimens

Caro Forero, Libardo Andrés; Martí Vargas, José Rocío; Serna Ros, Pedro (Elsevier, 2013-04)

This paper presents an experimental research work to evaluate prestress losses in pretensioned prestressed concrete. An experimental program including variables such as concrete mix design, specimen cross-section size and ...
Size Effect on Strand Bond and Concrete Strains at Prestress Transfer

Martí Vargas, José Rocío; Caro Forero, Libardo Andrés; Serna Ros, Pedro (American Concrete Institute, 2014)

[EN] The size-effect phenomenon has been analyzed with pretensioned prestressed concrete prismatic specimens at prestress transfer. An experimental program that includes variables such as concrete mixture design, specimen ...
Time-dependent evolution of strand transfer length in pretensioned prestressed concrete members

Caro Forero, Libardo Andrés; Martí Vargas, José Rocío; Serna Ros, Pedro (Society for Experimental Mechanics (SEM), 2013-11)

For design purposes, it is generally considered that prestressing strand transfer length does not change with time. However, some experimental studies on the effect of time on transfer lengths show contradictory results. ...
