Finite Element Analysis of Distortional Lateral Buckling of Continuous Composite Beams with Transverse Web Stiffeners
composite beams distortional lateral buckling transverse web stiffener U-frame action
2014/4/10
In a composite beam, transverse web stiffeners are often provided to the steel section at regular intervals along the beam span to eliminate local shear buckling as well as to reduce web distortion in...
Flexural performance of fire damaged and rehabilitated two span reinforced concrete slabs and beams
fire damage concrete continuous members rehabilitation flexural rigidity bearing capacity
2014/4/10
Five two-span reinforced concrete (RC) slabs and seven two-span RC beams were tested under the ISO 834 standard fire with different durations. CFRP strengthening was then applied to some of the specim...

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...
Moment redistribution and ductility of RHSC continuous beams strengthened with CFRP
RHSC continuous beam CFRP End anchorage Moment redistribution Ductility
2009/9/30
In continuous concrete beams, ductility allows redistribution of moment between the negative and positive moment zones. Although many in situ reinforced high strength concrete (RHSC) beams are of cont...
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...
