Abstract: This paper presents the experimental study of a new structure for a 10-m-span bridge deck, which takes into account the range of possibilities offered by new and high-strength materials along with the advantages of a ...

Abstract: The alkali-silica reaction (ASR) is a chemical reaction that causes expansions and unexpected deformations of concrete structures. A methodology of assessment of ASR-damaged structures is required in order to evaluate their ...

Abstract: The safety margin of shear design provisions for ultrahigh performance fiber reinforced concrete (UHPFRC) requires quantification prior to widespread use. To this aim, the results of a dedicated experimental campaign ...

Abstract: To quantify the safety margin of shear design provisions for ultrahigh performance fiber-reinforced concrete (UHPFRC), an experimental campaign has been performed. In a four-point bending configuration, shear tests have ...

Abstract: This paper presents a constitutive model for concrete in high-rate dynamics. The main feature outlined in this paper concerns the modeling of strength enhancement due to rate effects at the macrolevel of material description. ...

Abstract: An experimental research program was carried out in order to validate a methodology for the mechanical assessment of structures damaged by alkali-silica reaction (ASR). Long-term deformations of specimens kept under varied ...

Abstract: Ultrahigh-performance concrete (UHPC) offers significant potential to address a variety of needs in bridge design, construction, and performance enhancement. Bridge owners have shown willingness to embrace novel solutions ...

Abstract: This paper deals with the experimental determination of ductility of ultra-high-performance fiber-reinforced concrete (UHPFRC) columns with longitudinal passive reinforcement, tested under combined axial and alternate ...
