Influence of model uncertainty and long term deformations in action effects calculation in reinforced concrete structures
Most codes of practice adopt a semi probabilistic design approach for the dimensioning and assessment of structures. Accordingly, structural safety is ensured by performing limit state verifications using design values determined with adequately calibrated ...
EPFL2024Crack 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 ...
2023Influence of sustained loading on resistance and deformation capacity of reinforced concrete members in compression
Aurelio Muttoni, Xhemsi Malja, Miguel Fernández Ruiz
As acknowledged explicitly or implicitly in most of current design codes, a high level of sustained loading has a detrimental effect on the concrete compressive strength. However, its beneficial effect in terms of deformation capacity is neglected in most ...
ERNST & SOHN2022The 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 ...
EPFL2020A Contribution to the Design of Textile Reinforced Concrete Structures
The reduction of green-house gas emissions is one of the global challenges that our society is facing and the production of cement plays a major role because concrete is the most used material worldwide. For every 1000 kg of cement produced, 900 kg of CO2, ...
EPFL2020Influence of Load Duration on Shear Strength of Reinforced Concrete Members
Aurelio Muttoni, Miguel Fernández Ruiz, Darko Tasevski
The significance of sustained loading on the compressive and tensile strength of concrete has been experimentally verified since the 1950s and is currently acknowledged in most design codes implicitly or explicitly. However; its influence on other potentia ...
AMER CONCRETE INST2020Next generation synthetic fibers UHPFRC for sustainable structural applications
The ever-increasing demand for rehabilitation of existing structures and construction of new ones, along with environmental issues of the construction sites represent a heavy burden for society in terms of economy and environment. Meanwhile, Ultra-High Per ...
EPFL2019The mechanics of punching in reinforced concrete slabs and footings without shear reinforcement
João Tiago Ramos Bernardo de Santa Rita Simões
Punching shear failures of structural concrete members have been the focus of attention of numerous works presented over the last decades. Although various rational approaches have been developed to predict these failures, there is still no unanimity on a ...
