The research of bearing capacity of reinforced concrete beam with use combined experimental-computational method

open access: yesMATEC Web of Conferences, 2017
The article shows results of behavior research of reinforced concrete beam exposed to fire using standard “time-temperature” curve. Practice of fire resistance estimating for reinforced concrete beams based on experimental and calculation method was ...

Circular Innovations in Complex Systems: A Blueprint of Four Design Archetypes

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Circular innovations (CI), defined as the redesign of products, services or practices to minimise waste, reduce resource use and regenerate natural systems, are essential for advancing the circular economy. Despite growing recognition, their deployment in systems of linked parts with unpredictable interactions (complex systems) remains limited

Circular Economy in Crisis Contexts: An Assessment Framework for Post‐Disaster Building Stock Toward Strategic Autonomy

open access: yesBusiness Strategy and the Environment, EarlyView.
ABSTRACT Post‐disaster contexts generate large volumes of damaged building stock with significant, yet often unquantified, circularity potential. Through the lens of strategic management, the circular economy emerges as a transformative pathway to strengthen systemic resilience by reducing dependencies on external resources and mitigating supply chain ...

Shear transfer between precast prestressed bridge beams and in-situ concrete crosshead in continuous structures [PDF]

open access: yes, 1988
A detailed investigation was made to study the shear transfer between precast prestressed beams and in-situ concrete in a relatively new method of construction of continuous bridge decks where the ends of precast beams are connected to an integral in ...

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.

Craking of reinforced concrete beams

open access: yesInformes de la Construccion, 1969
Se pasa revista a diversas teorías existentes sobre fisuración, justificando al paso las fórmulas contenidas en la nueva Instrucción de Hormigón E. H. 68, recientemente aprobada en España con carácter interministerial. Se ofrecen diversas fórmulas y ábacos de comprobación y se exponen los trabajos más recientes del Comité Europeo del Hormigón sobre la ...

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.

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.
