Nonlinear Models of Reinforced and Post-tensioned Concrete Beams
Concrete post-tensioning finite element modelling
2009/2/20
Commercial finite element software generally includes dedicated numerical models for the nonlinear response of concrete under loading. These models usually include a smeared crack analogy to account f...
Non-linear analysis of externally prestressed concrete beams
Cable strain external cable unbonded deviator displacement
2009/2/20
In an external prestressing system, there is no strain compatibility between the cable and the concrete at every cross-section, the increment of cable strain must be evaluated by taking into account t...
The Effect of Detailing Steel in the CompressionRegions of Internal Supports on the Ductility ofReinforced Concrete Beams
Strengthening Ductility Reinforced concrete
2009/2/19
A clause on detailing in AS 3600 stipulates that 25 percents of the maximum steel in the span of a reinforced concrete beam has to be extended beyond the near face of each internal support. This sugge...
The effects of sulfate solution on the behavior of reinforced concrete beams
Crack Deflection Stiffness Sulfate solution
2009/2/18
Reinforced concrete structures can be adversely affected by chemical aggressive environments such as sulfates and chlorides. It is necessary to study the durability and some other critical engineering...
Behaviour of retrofitted reinforced concrete beams under combined bending and torsion : A numerical study
torsion numerical study
2009/2/17
This paper presents the numerical study on unretrofitted and retrofitted reinforced concrete beams subjected to combined bending and torsion. Different ratios between twisting moment and bending momen...
Flexural fatigue strength prediction of steel fibre reinforced concrete beams
steel fibre concrete beams
2009/1/14
Results of an investigation conducted to study the fatigue strength of steel fibre reinforced concrete (SFRC) containing fibres of mixed aspect ratio are presented. Approximately eighty one beam speci...
