Flexural Strengthening of RC Continuous T-Beams Using CFRP

Fibers, 2020
In this paper, experimental investigations for strengthening reinforced concrete (RC) continuous beams were performed. Eighteen T-beams were cast, twelve of which were inverted T-beams where the flange portion of the T-beam was subjected to positive ...

Unlocking Strength‐Toughness Dilemma in High‐Entropy Borides by Intragranular Microstructural Reconstruction

Advanced Science, EarlyView.
An extreme non‐equilibrium process combining heavy direct current sintering and TiSi2 addition is used to construct intragranular energy dissipation units within high‐entropy boride ceramics to overcome the strength‐toughness trade‐off. The resulting ceramic demonstrates attractive mechanical properties with a flexural strength of 887 MPa and a ...

The Influence of CFRP Anchorage on Achieving Sectional Flexural Capacity of Strengthened Concrete Beams

Fibers, 2015
This research program is intended to verify the influence of using distributed external U-wrap CFRP anchorage to shift the failure mode from overall debonding to sectional flexural failure for concrete beams externally bonded with CFRP sheets.

Bound Water as a Reinforcing Element for Ultra‐Strong Polyacrylamide

Advanced Science, EarlyView.
Rather than acting as a conventional plasticizer, bound water serves as a reinforcing element in polyacrylamide by constructing strong PAM–water–PAM hydrogen‐bond networks. This water‐mediated architecture delivers ultra‐high mechanical strength and exceptional flame resistance, redefining the role of water in polymer reinforcement.

Structural Behaviour of Strengthened Timber Beams With Fibre-Reinforced Polymer (FRP) and Steel: A Review

Advances in Civil Engineering
This paper provides a focused review of the studies on short-term flexural performance, creep behaviour and blast responses of timber beams reinforced with three strengthening methods: external reinforcement (ER), near-surface mounted (NSM) and glued-in (

Multimodal Bioinspired Self‐Healing Composites Enabling Durable and High‐Efficiency Wearable Perovskite Light‐Emitting Diodes

Advanced Science, EarlyView.
Butterfly wing–inspired intrinsically self‐healing polymer interlayers enable flexible perovskite optoelectronics with high luminance, strain‐insensitive stability, and environmental resilience. These hierarchically structured films redistribute mechanical stress, suppress defect formation, and maintain performance under repeated bending, paving the ...

Effective strengthening schemes for heat damaged reinforced concrete beams

Journal of King Saud University: Engineering Sciences, 2020
Several effective strengthening schemes for enhancing the flexural strength of heat-damaged reinforced concrete (RC), beams are proposed. A series of twenty-eight RC rectangular beams were cast, subject to a temperature of 600 °C for 3 h, strengthened ...

Self‐Assembly of Organic–Inorganic Copolymers Toward Bio‐Inspired Cementitious Composites

Advanced Science, EarlyView.
Organic–inorganic copolymerization of calcium silicate hydrate and thioctic acid produces a self‐organized nanocomposite inspired by the disordered collagen–mineral architecture of trabecular bone. The resulting material combines a compressive strength above 300 MPa with intrinsic physical reprocessibility, retaining over 80% of its strength and energy
