Size Effect in Reinforced Concrete Beams With Short Shear Span and Without Stirrups
Reinforced concrete Bazant's size effect theory Carpinteri's size eect theory
2009/10/14
For the to design of reinforced concrete beams with no stirrups, dierent equations have been formulated
by researchers. These equations either are on the side of extreme safety or do not include the...
Bond Strength of Tension Lap-Splices in Full Scale Self-Compacting Concrete Beams
Self-compacting concrete Bond strength Lap splice Full-scale beam Positive bending
2009/9/30
Twelve full-scale beam specimens (2000 × 300 × 200 mm) were tested in positive bending with the loading system designed to determine the effect of self-compacting concrete (SCC) and the diameter of re...
Nominal moment capacity of box reinforced concrete beams exposed to fire
Fire reinforced concrete nominal moment capacity beam box section cover concrete
2009/9/30
The performance of steel reinforced concrete (RC) beams with a box cross section exposed to fire is studied. The cross-section is divided into an appropriate number of segments so that non-uniform tem...
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...
