Structural Behavior of SFRC Beams strengthened with GFRP Laminates: An Experimental and Analytical Investigation

open access: yesBrazilian Archives of Biology and Technology
This paper presents the experimental results of a reinforced concrete beams (RC) strengthened with internal steel fibers (SF) and external glass fiber reinforced polymer laminates (GFRP). The research work studied the load carrying capacity, deformation,

Guided Toward Equity: Communities of Practice and Organizational Change in Community Colleges

open access: yesNew Directions for Community Colleges, EarlyView.
ABSTRACT Although community colleges advance equity by providing opportunities for marginalized students to pursue higher education, barriers to earning credentials remain, particularly for students of color. Higher education stakeholders are investing in “equity work” as organizations take responsibility for ensuring equitable outcomes.

The behaviour of reinforced concrete beams under cyclic temperature profiles [PDF]

open access: yes, 1986
On a hot summer day, high levels of solar radiation are incident on concrete bridge decks, causing non-linear variations in temperature through the depths of the structures. The changes in temperature lead to axial expansion and curvature of decks.

A Graph‐Based Generative Artificial Intelligence Methodology for Autocorrection of Utility‐System P&IDs

open access: yesChemie Ingenieur Technik, EarlyView.
This work explores generative AI for automated revision of Piping and Instrumentation Diagrams (P&IDs). We frame P&ID correction as a translation problem, converting attributed P&ID graphs into sequences and learning revisions with a transformer‐based model.

Assessment of Ultrasonic Pulse Velocity and Rebound Hammer Response in Steel–GFRP Hybrid Reinforced Concrete Beams

open access: yesBuildings
Non-destructive evaluation (NDE) methods are widely used to assess concrete quality, but their interpretation in reinforced concrete members remains challenging because measured responses may be influenced by reinforcement layout, casting and surface ...

Mechanism and disaster control new technology of strong ground pressure manifestation in ultra‐large mining face

open access: yesDeep Underground Science and Engineering, EarlyView.
In response to the problem of strong mining pressure manifestation along the goaf roadway in a thick coal seam mining area, this study uses a new type of combined blasting roof cutting technology to effectively control the manifestation and deformation of mining pressure along the goaf roadway.

Mitigating surcharge‐induced column‐head cracking in double‐deck shield tunnels using hyperelastic bearing joints

open access: yesDeep Underground Science and Engineering, EarlyView.
A staged three‐dimensional nonlinear soil–structure interaction (SSI) model is established, in which the initial geostress state, tunnel excavation, lining installation, delayed activation of the internal frame, and subsequent surcharge loading are simulated sequentially.
