Shear capacity of reinforced concrete corbels using mechanism analysis [PDF]

, 2012
A mechanism analysis is developed to predict the shear capacity of reinforced concrete corbels. Based on shear failure observed in experimental tests, kinematically admissible failure mechanisms are idealised as an assemblage of two rigid blocks ...

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

Experimental Testing and Strut-and-Tie Modeling of Full-Scale Precast Concrete Girders with FRP Repaired End Regions

Applied Sciences, 2020
Bridges located in cold regions are susceptible to extreme deterioration due to harsh climate conditions. Distressing of girder’s end regions is among the most common damage types in these bridges.

Experimental Verification of Strut and Tie Model Design Method [PDF]

ACI Structural Journal, 2007
Although strut-and-tie models (STM) appear to provide safe, lower-bound designs for irregular concrete members, there have not been many experimental validations of them. This paper presents the result from two series of testing of STM specimens. In the first series, 6 specimens having different reinforcing designs but the same overall geometry and ...

Verification of the bursting and spalling formulas in the FIB model code by finite element analyses of anchorage zones of pretensioned girders [PDF]

, 2016
In order to predict the stress and possible crack distribution in the anchorage zones of pretensioned girders several models have been developed as can be found in the fib Model Code, the ASHTOO code or Eurocode 2.

Thermal-structural design study of an airframe-integrated Scramjet [PDF]

Design concepts are developed and evaluated for a cooled structures assembly for the Scramjet engine, for engine subsystems mass, volume, and operating requirements, and for the aircraft/engine interface.

Performance-Based Optimization for Strut-Tie Modeling of Structural Concrete [PDF]

, 2002
Conventional trial-and-error methods are not efficient in developing appropriate strut-and-tie models in complex structural concrete members. This paper describes a performance-based optimization (PBO) technique for automatically producing optimal strut ...

Numerical analysis of reinforced concrete dapped-end beams [PDF]

Revista IBRACON de Estruturas e Materiais
The reinforced concrete dapped-ends present in beams, being regions of discontinuity, require non-trivial models for their analysis and design, such as the strut-and-tie model, the shear-friction model, and the finite element method.

Evaluation of strut-and-tie modeling for bridge pier applications [PDF]

, 2002
Strut-and-tie modeling is an analysis and design tool for reinforced concrete elements which assumes that internal stresses are transferred through a truss type mechanism.
