Structural Concrete, EarlyView.Abstract In precast concrete structures, optimizing the design of corbels by considering the contributions of secondary reinforcement elements can significantly improve construction economy, especially when corbels are repeated multiple times. This paper proposes a strut‐and‐tie model for reinforced concrete corbels subjected to vertical and/or ...

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

Rotation capacity of continuous reinforced concrete slab strips revisited
Structural Concrete, EarlyView.Abstract Rotation capacity is a key characteristic of statically indeterminate reinforced concrete structures, as it (i) enables bending moment redistributions, whether intentionally introduced through optimized reinforcement layouts or arising from unforeseen self‐equilibrated stress states, and (ii) promotes large rotations at failure load, thereby ...

The challenges of GFRP RC beam design for limit states
Structural Concrete, EarlyView.Abstract Glass fiber reinforced polymer (GFRP) bars are used ever more frequently in concrete construction due to their non‐corrosive and anti‐magnetic properties. Their research over the past decades focused on fundamental questions, such as the design aspects of beams under flexural loads.

Structural Concrete, EarlyView.Abstract The acoustic emission (AE) technique has proven to be an effective method for detecting individual wire breaks in prestressed concrete structures affected by stress corrosion cracking (SCC). However, despite its widespread application, the quantitative assessment of AE monitoring reliability and optimal sensor placement remains unresolved ...

Structural Concrete, EarlyView.Abstract During their life cycle, prestressed concrete bridges are prone to wire breaks of their tendons due to fatigue or stress corrosion cracking. However, not all structures show visible cracking on the surface, which would provide timely warning of otherwise invisible damage. Brittle failure may occur.

Effective axial strength of laterally strengthened RC pier heads with post‐tensioning method
Structural Concrete, EarlyView.Abstract This study investigates the structural performance enhancement of reinforced concrete (RC) pier heads laterally strengthened with unbonded post‐tensioning (PT) to accommodate increased design loads following a deck replacement of an existing railway bridge.

Cracking and Crushing in Prestressed Concrete Beams
ACI Structural Journal, 2021The cohesive/overlapping crack model represents an effective tool in the study of failure transition phenomena occurring in plain or reinforced concrete structures. In the present paper, this non-linear fracture mechanics model is applied to study the global structural behavior of prestressed concrete beams casted by means of pre-tensioning technique ...

Design of reinforced concrete beams
1996Reinforced concrete beam design consists primarily of producing member details which will adequately resist the ultimate bending moments, shear forces and torsional moments. At the same time serviceability requirements must be considered to ensure that the member will behave satisfactorily under working loads.

Damage modelling of reinforced concrete beams
Advances in Engineering Software, 2007Analysis of reinforced concrete building floor frames can be significantly improved when appropriate material models are assumed to represent the actual global behaviour and consequently to improve the ultimate and serviceability limit state verifications.
