    A higher-order equation for modeling strand bond in pretensioned concrete beams 
    Ramirez-Garcia, Alberto T.; Dang, Canh N.; Hale, W. Micah; Martí Vargas, José Rocío (Elsevier, 2017)
    [EN] In pretensioned concrete members, the bond between prestressing strands and concrete in the transfer zone is necessary to ensure the two materials can work as a composite material. This study develops a computer program ...

    A New Smoothing Technique for Transfer-Length Determination 
    Ramirez-Garcia, Alberto T.; Dang, C.N.; Deschenes, R.A.; Hale, W. M.; Martí Vargas, José Rocío (American Concrete Institute, 2018)
    [EN] Transfer length is a significant parameter in the design of pretensioned concrete members. This study reports the measured transfer length of 15.2 mm (0.6 in.) prestressing strands. Twenty-four pretensioned concrete ...

    Assessment of transmission length of prestressing strands according to fib Model Code 2010 
    Dang, Canh N.; Hale, W. Micah; Martí Vargas, José Rocío (Elsevier, 2017)
    [EN] The use of 18-mm prestressing strands is advantageous in the construction of long-span bridges. Transmission length is a significant parameter in the design of pretensioned concrete members. This study provides a ...

    Bond mechanism of 18-mm prestressing strands: New insights and design applications 
    Dang, Canh N.; Martí Vargas, José Rocío; Hale, W. Micah (Techno-Press, 2020-10-10)
    [EN] Pretensioned concrete (PC) is widely used in contemporary construction. Bond of prestressing strand is significant for composite-action between the strand and concrete in the transfer and flexural-bond zones of PC ...

    Bond Stress-Slip Model for 0.6 in. (15.2 mm) Diameter Strand 
    Dang, CN; Floyd, RW; Murray, CD; Hale, WM; Martí Vargas, José Rocío (AMER CONCRETE INST, 2015)
    In pretensioned concrete members, strand bond is necessary for transferring prestress force from the prestressing strands to the adjacent concrete. This paper proposes a new bond stress-slip model for 0.6 in. (15.2 mm), ...

    Measured Development Lengths of 0.7 in. (17.8 mm) Strands for Pretensioned Beams 
    Dang, Canh N.; Floyd, Royce W.; Micah Hale, W.; Martí Vargas, José Rocío (2016-01)
    The use of 0.7 in. (17.8 mm), Grade 270 (1860) prestressing strands in construction is slow regardless of the engineering advantages of these types of strands. The limited research data and unavailable design guidelines ...

    Measured Transfer Lengths of 0.7 in. (17.8 mm) Strands for Pretensioned Beams 
    Dang, C.N.; Floyd, R.W.; Hale, W. M; Martí Vargas, José Rocío (American Concrete Institute, 2016-01)
    [EN] The use of 0.7 in. (17.8 mm), Grade 270 (1860) prestressing strands has advantages over 0.5 and 0.6 in. (12.7 and 15.22 mm) strands. This study provides design guidelines for estimating transfer length of 0.7 in. (17.8 ...
