Rotation capacity of continuous reinforced concrete slab strips revisited

Structural Concrete, EarlyView.
Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

Nonlinear finite element modeling and parametric analysis for the design implication of expanded rib steel bars in RC beams

Developments in the Built Environment, 2023
The quest for innovative design of reinforced-concrete to make it more durable, flexible, and sustainable has brought a transition from traditional methods of lap splicing to the use of anchor-head bars.

The challenges of GFRP RC beam design for limit states

Structural Concrete, EarlyView.
Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Variation of Splice Length with Bending Behavior of Reinforced Concrete Beams [PDF]

, 2019
The splice length of the distribution depends on the concrete stress with reinforcement, generally the bond stress is tested by pull out testing where pull out testing can provide a good comparison between the efficiency of the attachment of various ...

Recent Advances in Photocatalyst‐Driven Protein Labeling and Proximity Mapping

The Chemical Record, EarlyView.
Photocatalyst‐driven protein labeling and proximity mapping have rapidly advanced as powerful strategies for spatiotemporal control in complex biological environments. This review integrates recent developments across single‐electron transfer and energy transfer‐based mechanisms and highlights how catalyst design, reactive intermediates, and diffusion ...

Bond strength of lap spliced steel bars in RC beams strengthened with low-cost natural FRP composites: Experimental and theoretical study

Case Studies in Construction Materials
Natural FRPs have proven their prospective in enhancing the compressive behavior of concrete. However, their effectiveness in preventing brittle steel lap splice failure has not been investigated. This study utilizes low-cost hemp and cotton eco-friendly

The choice to submit: freedom, gender, and the figure of God in Pentecostal Nigeria Le choix de se soumettre : liberté, genre et figure divine chez les Pentecôtistes du Nigeria

Journal of the Royal Anthropological Institute, EarlyView.
Why do some women choose to submit to their husbands in marriage? In anthropology, the paradox of ‘chosen submission’ has famously been explored by Saba Mahmood. Her work amongst Egyptian women donning the veil in the Islamic da'wa movement spotlights the notion of ‘piety’ to explore how devotion to God can act as a powerful motivator of human ...

Test Results and Comparison to Code Equations on Lap Splice Strength of Reinforcement in RC beams [PDF]

, 2021
The design of the lap splices will have a major change with the 2nd generation Eurocode prEN 1992-1-1 D7. One of the changes in prEN1992-1-1 D7 is the effect of the proportion of the lapped bars in tension in one cross-section. In the current Eurocode, a

Evaluating the Splice Effect on the Flexural Performance of RC Beams Reinforced with Hybrid and GFRP Rebars

International Journal of Concrete Structures and Materials
Lap splices play a critical role in the flexural performance of reinforced concrete (RC) members, particularly when non-ductile reinforcement, such as glass fiber-reinforced polymer (GFRP) bars, is used.
