Experimental and numerical analysis of reinforced concrete

The main conclusion of this experimental and numerical study was that the fire resistance of RC beams always increases when any type of restraint (axial or axial plus rotational) is introduced. In addition, by fixing the rotational stiffness, the beams with higher axial stiffness level presented higher fire resistance than those with the lower level. Experimental and numerical investigations of axial pullout Buried pipelines often cross active landslide areas, which are subjected to additional loads due to ground movements. The effect of ground loads on the performance of buried pipelines is an important consideration for pipeline integrity assessment. Though experimental and analytical studies were conducted to understand the maximum loads caused by the ground movement on the pipelines, Experimental and numerical studies on axially restrained Experimental and numerical studies on the fire resistance of cold-formed steel (CFS) columns with built-up box-shape sections were conducted in this paper. Experimental and numerical studies on the lateral Jan 17, 2020 · Experimental and numerical studies on the lateral performance of concrete sandwich walls. Gang Xu. The responses obtained by the FEA models match well with the experimental results. The stiffness and load capacity of sandwich wall are increased, but the ductility is reduced when the axial load is increased; the deformation capacity can be

Experimental and numerical study of soil-reinforcement

Oct 27, 2006 · Numerical simulations and experimental results clearly identify a critical zone between 0.3 and 0.5B, where maximum benefits not only on the bearing capacity but also on the low-strain stiffness of the foundation are obtained. Therefore, soil reinforcement can also be used to reduce low-strain vibrations of foundations.
