Reliability analysis of strut-and-tie models for the design of deep beams according to NBR 6118 (2023) [PDF]
Revista IBRACON de Estruturas e MateriaisThe strut-and-tie method (STM) applied in the structural design of deep beams is a semi-probabilistic method, that does not take directly into account both the uncertainties associated with the variables involved and those inherent in the calculation ...

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

10th East Asia-Pacific Conference on Structural Engineering and Construction: Materials, Experimentation, Maintenance and Rehabilitation (EASEC-10) [PDF]
, 2006 This paper presents the performance-based optimization of strut-and-tie models in reinforced concrete beam-column connections. The performance-based optimization (PBO) technique is employed to investigate optimal strut-and-tie models in reinforced ...

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.

Reinforced concrete corbels strengthened with external prestressing
Revista IBRACON de Estruturas e Materiais, 2019 Reinforced concrete structures may demand, throughout their lifetime, the increase of the capacity load due to eventual changes in the load configuration. In this context, corbels could be considered structural elements which present great challenges for

Structural Concrete, EarlyView.Abstract Reinforced concrete (RC) dapped‐end connections feature a sharp re‐entrant corner subjected to high stress concentrations, leading to wide cracks under service loads and potential durability issues such as reinforcement corrosion. Effective crack control is therefore essential in the design of new dapped‐end connections. Steel fiber reinforced

Strut-and-tie model for punching shear of concrete slabs
, 1995 The reinforced concrete slab system is an economical and popular structural slab system in building and offshore construction. A major concern of this system is localized punching shear failure at the slab-column interface.

Three‐parameter kinematic theory for shear assessment of reinforced concrete short columns
Structural Concrete, EarlyView.Abstract This work presents a rational kinematics‐based model for assessing the shear capacity of rectangular reinforced concrete short columns. Due to their high stiffness and brittleness, short columns are particularly vulnerable to seismic forces, often exhibiting critical failures.

Improvement and Application of the Softened Strut-and-Tie Model
IOP Conference Series: Materials Science and Engineering, 2017 Previous experimental researches indicate that reinforced concrete beam-column joints play an important role in the mechanical properties of moment resisting frame structures, so as to require proper design. The aims of this paper are to predict the joint carrying capacity and cracks development theoretically.

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
