A Model for Sustainable Development in Territorial Production Systems

open access: yesSustainable Development, EarlyView.
ABSTRACT The territorial production system demand innovation and adaptability to provide the majority of decisions, especially when splitting up available resources among productive sectors by the lens of sustainable development. The system's economic units evolve in dimensional profile, technical execution, and management of productive process to ...

Rate‐type and integral‐type sectional analysis for time‐dependent response with the fib Model Code 2020

open access: yesStructural Concrete, EarlyView.
Abstract This study examines the time‐dependent behavior of reinforced and prestressed concrete structures using integral‐ and rate‐type formulations, applying the concrete creep and steel relaxation models from the fib Model Code 2020. The stress–strain law for aging concrete is expressed by a second‐order differential equation, but a single rate‐type

Shear transfer model for ultra‐high‐performance concrete incorporating fiber bridging mechanism

open access: yesStructural Concrete, EarlyView.
Abstract Ultra‐high‐performance concrete (UHPC) exhibits exceptional mechanical properties, including high shear strength, partly attributed to the fiber bridging mechanism. However, existing shear transfer models for normal‐strength concrete have not considered the significant contribution of fibers.
