RISAnalytical Model for Predicting Response and Flexure-Shear Resistance of Composite Beams Combining Reinforced Ultrahigh Performance Fiber-Reinforced Concrete and Reinforced Concrete
Publisher: American Society of Civil Engineers
Abstract: The addition of an external layer of reinforced ultrahigh performance fiber-reinforced concrete (R-UHPFRC) on top of reinforced concrete (RC) floor slabs and bridge decks is an emerging technique for strengthening RC ...
Inverse Analysis of R-UHPFRC Beams to Determine the Flexural Response under Service Loading and at Ultimate Resistance
Publisher: ASCE
Abstract: Ultra high performance fiber reinforced cementitious composites (UHPFRCs) have demonstrated their outstanding efficiency as structural materials. Determination of the bending resistance of members combining UHPFRC with ...
Structural Response of Elements Combining Ultrahigh-Performance Fiber-Reinforced Concretes and Reinforced Concrete
Publisher: American Society of Civil Engineers
Abstract: The use of ultrahigh-performance fiber-reinforced concretes (UHPFRC) improves the structural response and extends the durability of concrete structures. Three basic configurations for structural elements combining UHPFRC ...
Geometrical and Material Characterization of Quenched and Self-Tempered Steel Reinforcement Bars
Publisher: American Society of Civil Engineers
Abstract: Quenched and self-tempered (QST) steel reinforcement bars (rebars) are manufactured by Thermex or Tempcore processes. Characterization studies of QST rebars are mostly limited to reveal the hardened outer layer and some ...
Brine Absorption in Concrete at Low Temperature: Experimental Investigation and Modeling
Publisher: American Society of Civil Engineers
Abstract: An experimental campaign supports a model named TransChlor for bringing liquid water moved by capillary suction and chloride ions into concrete. The principal objective of the experimental campaign is to represent conventional ...
Fracture of AAC as Influenced by Specimen Dimension and Moisture
Publisher: American Society of Civil Engineers
Abstract: An experimental investigation into fracture of autoclaved aerated concrete (AAC), a lightweight building material, is presented. The experiments indicate that AAC is a softening material, and the fracture process can be ...
Supply and Demand System Approach to Development of Bridge Management Strategies
Publisher: American Society of Civil Engineers
Abstract: A supply and demand system approach is presented to deal with the inability of existing bridge management systems to determine optimal management strategies when multiple bridges may be adversely affected simultaneously. ...
Effect of Common Cause Failures on Indirect Costs
Publisher: American Society of Civil Engineers
Abstract: Next generation bridge management systems will take into consideration multiple hazard scenarios and not only traffic loading and structural deterioration as they do now. The indirect costs used in these bridge management ...
Geometrical and Material Characterization of Quenched and Self-Tempered Steel Reinforcement Bars
Publisher: American Society of Civil Engineers
Abstract: Quenched and self-tempered (QST) steel reinforcement bars (rebars) are manufactured by Thermex or Tempcore processes. Characterization studies of QST rebars are mostly limited to reveal the hardened outer layer and some ...
Fracture Model Evaluation of Dam Concrete
Publisher: American Society of Civil Engineers
Abstract: The following fracture models are assessed on the basis of an extensive testing program of large wedge‐splitting specimens: Bažant's size effect law; Hil‐lerborg's fictitious crack model; Carpinteri's brittleness model; ...
