    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 ...

    Effect of concrete compressive strength on transfer length 
    Ramirez-Garcia, Alberto T.; Floyd, R.W.; Hale, W. M.; Martí Vargas, José Rocío (Elsevier, 2016)
    [EN] This paper examines the effect of concrete compressive strength on the transfer length of prestressing strands. The paper includes the results from several research projects conducted at the University of Arkansas ...

    Influence of concrete strength on development length of prestressed concrete members 
    Ramirez-Garcia, Alberto T.; Floyd, R.W.; Hale, W. M.; Martí Vargas, José Rocío (Elsevier, 2016)
    [EN] Fifty seven prestressed concrete beams were fabricated at the University of Arkansas (UA) to determine the influence of concrete strength on the development length of seven wire prestressing strand. The variables ...
