Load–deflection curveRust elementFlexural strengthUltimate deflectionThis paper presents a finite element study of corroded concrete beam flexural behaviour in which the influence of the percentage of corrosion on the load鈥揹eflection curve was studied. CASTEM 2000 computation software was used and the...
The load–deflection curves of the test specimens are given in Fig.8. All of them were approximately linear after the first cracking. In RC beams with openings, the load abruptly dropped due to brittle shear failure. However, in RGm and RGh, the load–deflection curve became horizontal with ...
Fig. 6 provides the load–deflection (mid-span deflection) curves for all of the beams. The load–deflection behavior initially resembles that of an uncracked beam. The curve development in this segment is regarded as steeply linear. After the first section, as can be seen, these curves began...
3.1. Load–deflection curves The load-deflection curves of all tested beams are presented in Fig. 7a–d. All curves in Fig. 7 were characterised by three distinct stages (ascending branches with decreasing slope) up to the maximum load: (1) Stage I: un-cracked beam; (2) Stage II: deve...
Results of RC-1 beam: (a) FEM failure pattern, (b) experiment failure pattern, and (c) load-deflection response. The analysis results show that the concrete adopts the total strain crack model and the steel bar adopts the von Mises model, which can well simulate the control members. 3.5...

Deformation is another crucial aspect of flexural behavior. The beam's ductility can be quantified by measuring the mid-span deflection relative to the steel yield point. This measurement was established by examining the corresponding flexural strain gauge readings and load–deflection curve, as well ...
Deflection Testing To validate consistent DC resistance over extended cycling, Ardent performed extensive cycle testing with resistance measurements taken at various intervals. Board Wear is one of the biggest challenges customers face when using a rocking beam style contact system. RC Scrub‐R ...
And it has less effect on the decrease in the load carrying capacity. 5.2. Ductility analysis The displacement ductility coefficient (μ) could effectively quantify the deformation capacity of an RC beam before ultimate failure. It was defined as the ratio of the ultimate deflection (Δu) to ...
The shear strength of beam P-3d-2ϕ25 (Fig. 3b) with a single point load at 3d was least and beam P-1.5d-2ϕ25 (Fig. 3a) with a single point load at 1.5d greatest. The load deflection curves of each beam are shown in Fig. 3. Deflections at LVDT#6, which was positioned ...
