Crack kinematics prediction in concrete structures and assessment of their criticality
The observation of cracks in normally functioning reinforced concrete (RC) structures is expected as the tensile strength of concrete is relatively low. However, one or more of those cracks can start to propagate with increasing crack openings, localizing ...
2023The influence of the kinematics of rough surface engagement on the transfer of forces in cracked concrete
One of the most instrumental aspects governing the response of structural concrete at ultimate limit state refers to the possibility of developing smeared cracking patterns within a member (associated normally to the presence of sufficient reinforcement fo ...
2021On the compressive and bond strength of reinforced concrete as structural properties
Francesco Rafael Alberto Moccia
Traditionally, the concrete strength is measured on cubes or cylinders having normalized dimensions, suitable vibration and curing conditions and their strength is assessed in laboratory under fast loading rates. However, the in-situ strength of structural ...
EPFL2021Static and Fatigue Biaxial Flexural Behavior of Strain-Hardening UHPFRC Thin Slab Elements
Cast-in-place thin layers of Ultra-High Performance Fiber Reinforced Cementitious Composites (UHPFRC) on the specific zones of existing reinforced concrete (RC) bridge decks has been demonstrated to be a technically efficient and economic rehabilitation an ...
EPFL2020Cold stiffening of orthotropic steel decks by a composite UHPFRC layer
Eugen Brühwiler, Lan Duan, Shichao Wang
Cold stiffening of the plate of Orthotropic Steel Deck (OSD) of bridges can be achieved by adding a layer of Ultra-High Performance Fiber Reinforced Cementitious Composite material (UHPFRC) on top of the deck plate by composite design, thus expecting to re ...
ELSEVIER SCI LTD2020Efficiency Factors for Plastic Design in Concrete: Influence of Brittleness in Compression, High Tech Concrete: Where Technology and Engineering Meet
Aurelio Muttoni, Miguel Fernández Ruiz, Francesco Rafael Alberto Moccia
A large number of design approaches for structural concrete rely on the applicability of limit analysis. This is for instance the case of bending and shear design in members with transverse reinforcement, where it is assumed that plastic compression fields ...
2017An experimental investigation into bond behavior of prestressed CFRP to steel substrate
Ardalan Hosseini, Masoud Motavalli, Elyas Ghafoori
Nowadays, strengthening of existing steel structures using advanced carbon fiber reinforced polymer (CFRP) composites is becoming a common technique due to the unique advantages of the material such as light weight, high strength and fatigue endurance, as ...
2017Geometrical and material characterisation of quenched and self-tempered steel reinforcement bars
Eugen Brühwiler, Alain Nussbaumer, Marina Rocha Pinto Portela Nunes
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 improved mechanical properties compa ...
Asce-Amer Soc Civil Engineers2015Temperature effects on material properties and structural response of polymer matrix composites
Structural components used in civil engineering applications are often subjected to compressive loads. Unlike the tensile strength of fiber-reinforced polymer (FRP) materials, their compressive strength is resin-dominated, exhibiting lower values and more ...
EPFL2015Design criterion for fatigue strengthening of riveted beams in a 120-year-old railway metallic bridge using pre-stressed CFRP plates
Alain Nussbaumer, Gary Scott Prinz, Andrin Herwig, Elyas Ghafoori
This study presents a design criterion developed for fatigue strengthening of a 120-year-old metallic railway bridge in Switzerland and presents a pre-stressed un-bonded reinforcement (PUR) system developed to apply the strengthening. The PUR system uses c ...
