Strip loading in reinforced concrete: Mechanical modeling and experimental validation

Structural Concrete, EarlyView.
Abstract Strip loading of reinforced concrete is a common problem in engineering practice. The concrete compressive strength at the load introduction can be several times higher than the uniaxial concrete compressive strength, which can be attributed to geometrical and passive confining stresses caused by load dispersion and reinforcement, respectively.

Critical shear crack shapes in slender reinforced concrete beams with and without shear reinforcement

Structural Concrete, EarlyView.
Abstract The accurate prediction of the shear capacity of reinforced concrete underpins the efficient and safe design of concrete buildings and infrastructure. Disagreement remains about shear mechanisms and the modeling of shear resistance. For slender beams without shear reinforcement, critical shear crack (CSC) models have attracted interest.

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

Structural 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

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

Structural 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 ...

Experimental investigation of reinforced concrete members subjected to reversed cyclic axial loading

Structural Concrete, EarlyView.
Abstract This paper presents an experimental campaign of five reinforced concrete members subjected to cyclic axial loading alternating between tension and compression. Fiber optical sensors and digital image correlation, in combination with automated crack detection and measurement, were used to investigate, among other aspects, the development of ...

Numerical analysis of the effects of corrosion on the punching shear capacity of reinforced concrete flat slabs with openings

Structural Concrete, EarlyView.
Abstract The reinforcement corrosion is one of the main degradation mechanisms in reinforced concrete structures. Its effects can harm structural elements by reducing mechanical capacity, mainly due to diminished reinforcement properties and expansive reactions within the concrete.
