Long-Term Performance of Prestressed, Pretensioned High Strength Concrete Bridge Girders

Abstract: Note: Whereas Reference 4 refers to "basic principles," Reference 5 applies to "advanced principles" in connection with continuity, ultimate design, building codes, structural steel and so forth.

“…2 The application to prestressed, pretensioned highstrength concrete bridge girders was studied in the 1990s. 3 The result of this study was that high-strength concrete bridge girders can be expected to perform adequately over the long term, but that further research into the creep and shrinkage characteristics of high-strength concrete is required. A decade later, results of high-performance lightweight concrete pretensioned bridge girders were reported.…”

“…Research on the structural applications of high‐strength concrete with cube compressive strengths of 100 MPa has been carried out, first on reinforced concrete beams, since the 1970s . The application to prestressed, pretensioned high‐strength concrete bridge girders was studied in the 1990s . The result of this study was that high‐strength concrete bridge girders can be expected to perform adequately over the long term, but that further research into the creep and shrinkage characteristics of high‐strength concrete is required.…”

“…Estos efectos contrarios hacen que las deformaciones a largo plazo en HLAD sean difíciles carga inicial aplicada. Roller et al (1993) y Roller et al (1995), midieron las pérdidas de pretensado en vigas pretensadas hechas con HAD. Después de 18 meses de mediciones ellos concluyeron que las pérdidas de pretensado debidas a creep y retracción fueron de sólo 2.5 %.…”
