Kinematics‐based model for shear capacity assessment of unreinforced interior beam–column joints

Structural Concrete, EarlyView.
Abstract This study presents a kinematics‐based model for assessing the shear strength of reinforced concrete interior beam–column joints without transverse reinforcement. The proposed framework is built on first principles—kinematics, equilibrium, and constitutive relations—and explicitly models discrete cracks by introducing kinematic parameters such

Influence of shear reinforcement detailing on the shear capacity of reinforced concrete beams

Structural Concrete, EarlyView.
Abstract Alternative shear reinforcement layouts that do not fully enclose the longitudinal tensile reinforcement can significantly improve the constructability of reinforced concrete (RC) members. However, their influence on shear transfer mechanisms is not yet fully understood. To address this gap, an experimental program comprising 10 shear tests on

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 ...

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.
