Regression‐based models for the torsional stiffness reduction factor in reinforced concrete beams under combined torsion and shear

Structural Concrete, EarlyView.
Abstract This paper presents a regression‐based methodology to estimate the Torsional Stiffness Reduction Factor (TSRF) of reinforced concrete beams under combined torsion and shear. A numerical database of 6816 samples was generated using the Combined Action Softened Truss Model (CA‐STM) implemented in Python, considering design guidelines prescribed ...

Evaluating structural resistance and updating modeling uncertainties through testing

Structural Concrete, EarlyView.
Abstract The aging of infrastructure necessitates a robust and rational methodology for the assessment of existing structures. Design codes provide general models which cover different design scenarios and are thus overly conservative. Also, such design approaches lack field data and, if applied directly to existing works, often lead to unnecessarily ...

Shear capacity of reinforced concrete one‐way slabs with intermediate support and distributed loading

Structural Concrete, EarlyView.
Abstract Experimental campaigns on reinforced concrete members, being the basis for database evaluations used for validation of many shear design approaches, mostly include simply supported single‐span beams with concentrated loads. Other support and loading conditions representative for actual slab systems are highly underrepresented.

Quantifying the embodied‐carbon premium of RC transfer beams via automated design

Structural Concrete, EarlyView.
Abstract Transfer structures in reinforced concrete (RC) buildings enable architectural flexibility but often increase material use and embodied carbon. This study introduces an automated framework to quantify the embodied‐carbon premium associated with such systems. For each parametric configuration, two equivalent RC frames—one regular and one with a

Behavior of exterior beam‐column joint reinforced with shape memory alloy

Structural Concrete, EarlyView.
Abstract Beam‐column joints are critical regions in moment‐resisting frames and are particularly susceptible to severe stress concentrations and reinforcement congestion. Conventional design typically relies on dense transverse reinforcement to improve joint performance, resulting in construction difficulties and reinforcement congestion.

Damping ratio of reinforced concrete walls under limited damage from shaking table test and data‐driven modeling

Structural Concrete, EarlyView.
Abstract Accurate estimation of the damping ratio is critical for evaluating floor response spectra and equipment seismic demands in nuclear power plant structures. This study investigates the elastic damping ratio of reinforced concrete walls under limited damage states through shaking table tests and data‐driven modeling.

Accelerating Mission Engineering: Evidence of a Stratified Landscape and a Path Toward Unified Practice

Systems Engineering, EarlyView.
ABSTRACT Mission Engineering is maturing as a Systems Engineering discipline, yet adoption of its common frameworks remains stratified. This study examines whether selective adoption is observable across ME scholarship and develops a framework to address identified barriers.
