Performance analysis of strengthening reinforced concrete beams under pure torsion using galvanized steel sheets: Experimental and numerical investigation

open access: yesStructural Concrete, EarlyView.
Abstract Reinforced concrete (RC) beams can be subjected to torsion, and failure due to torsion is brittle and poses a significant risk to occupants. Moreover, strengthening of existing RC beams in torsion may be required due to the upgrade of the structures or as part of structural rehabilitation.

Modeling the response of UHPC shear‐critical beams: Integrating nonlinear finite element analysis and artificial neural network

open access: yesStructural Concrete, EarlyView.
Abstract An analytical framework suited for the analysis of shear‐critical ultra‐high performance concrete (UHPC) members is presented. The numerical methodology utilizes a nonlinear finite element analysis formulation integrated with an artificial neural network (ANN) that characterizes the UHPC tension response based on its mix design. In addition, a

Punching shear in flat slab systems – Experimental quantification of unconsidered system influences

open access: yesStructural Concrete, EarlyView.
Abstract Due to the demand for slender and functional buildings, flat slabs are a frequently used load‐bearing element in buildings. However, the concentrated load introduction at the slab‐column connection is often the governing detail in design due to punching shear failure.

Impact of half‐joint failures on RC girder bridges: A robustness quantification study

open access: yesStructural Concrete, EarlyView.
Abstract The robustness of bridge structures is critical to ensuring safety and service continuity, particularly in aging infrastructure exposed to degradation and unexpected loads. Reinforced concrete (RC) half‐joint bridges—widely built in Italy between the 1950s and 1970s—exhibit specific vulnerabilities due to inspection challenges, durability ...

Strip loading in steel fiber reinforced concrete: Experimental and theoretical investigation

open access: yesStructural Concrete, EarlyView.
Abstract Fiber reinforced concrete is becoming increasingly popular in engineering practice due to its high robustness, post‐cracking behavior, and crack control. For strip loading, as common, for example, in longitudinal joints of tunnel lining segments, the use of fiber reinforced concrete has the potential to reduce conventional reinforcement ...
