Finite-Element Analysis of Shear-off Failure of Keyed Dry Joints in Precast Concrete Segmental Bridges [PDF]

, 2014
This article has been made available through the Brunel Open Access Publishing Fund.The structural behaviour of precast concrete segmental bridges is largely dependent on the behaviour of the joints between segments.

Strength evaluation of concrete corbels cast in a different stage from the column

Revista IBRACON de Estruturas e Materiais
The design of a precast structural system requires joints between the structural elements, and concrete corbels are commonly used in the connection between beams and columns.

Shear Strengthening of Corbels with Carbon Fibre Reinforced Polymers (CFRP)

Materiales de Construccion, 2010
Corbels constitute what are known as “disturbed” regions in concrete structures, where typical shear failure may be anticipated on the grounds of small shear span-to-depth ratios.

Behavior of Reinforced Concrete Corbels Strengthened with CFRP Strips Subjected to Monotonic and Repeated Loading

Tikrit Journal of Engineering Sciences
Concrete corbels are short cantilevers subjected to monotonic and repeated loads. Repeated loads generally negatively affect the concrete structural members' strength as they decrease the resistance to external loads.

Further refinement of the Corbelling Theory for the equilibrium analysis of corbelled domes [PDF]

Curved and Layered Structures, 2019
Abstract The aim of this paper is to present a further development of the Corbelling Theory [1] for assessing the structural safety of “false domes” constructions like Trulli, and more generally for corbelled domes. In particular, it is well-known that a corbelled dome of a Trullo is a layered thick shell and that only the thin inner ...

Reinforced Concrete Corbels Shear Test: The Triangular-Truss Method Evaluation

Buildings, 2022
In this paper, five reinforced concrete double-corbel specimens with the same designed bearing capacity are produced according to the triangular-truss method (TTM) in GB 50010-2010.

An Archaeometric Approach to Reveal Organic Compounds via GC‐MS Analyses of Two Discovered Incense Burners at Daba Al‐Bayah

Archaeometry, EarlyView.
ABSTRACT This study focuses on two terracotta incense burners discovered in the Daba Al‐Bayah necropolis in the Musandam Peninsula (Oman), associated with an Iron Age collective tomb (LCG‐2). Through gas chromatography–mass spectrometry (GC‐MS), the organic residues preserved within these artifacts were analyzed to investigate their use and ...

SHALLOW FLAT SOFFIT PRECAST CONCRETE FLOOR SYSTEM [PDF]

, 2014
A precast concrete floor system that eliminates the need for column corbels and beam ledges while being very shallow. The main advantages of the present system include a span to-depth ratio of 30, a flat soffit, economy, consistency with prevailing ...

Optimizing different damaged reinforced concrete corbel characteristics utilizing CFRP sheets

Fracture and Structural Integrity
Concrete corbels are short cantilever constructions that may lose their strength over time because of loads that happen over and over again. As an external bonding method for reinforcement, carbon fiber-reinforced polymer (CFRP) strips are utilized to ...
