Development of a multi-axial load distribution measurement device
… poor predictors and there is evidence that shear load is at least equally important in ulcer development. Compared to the numerous commercial systems available for plantar pressure distribution measurement, only a few experimental devices exist for shear distribution measurement. These are …

Behavior of concrete-filled pvc tube columns under axial load
… offers numerous advantages due to its large axial stiffness and capacity. In the system, steel is a common type of material and has been widely used. However, the application of FRP and PVC came into the picture as the alternative to the steel application in the system. In this study, the …

Axial load transfer in large scale physical model drilled shaft foundations
… type of deep foundation used to support heavy loads from superstructures such as buildings and bridges. Uncertainties exist in the axial load transfer behavior of drilled shafts subject to loading and unloading cycles. A better understanding of the changes in soil reload stiffness can lead to a …

Axial load capacity of circular steel tube columns filled with high strength concrete
This study examines the axial load capacity of circular Concrete Filled Steel Tube columns using High Strength Concrete (CFST-HSC). Emphasis is drawn to the enhanced axial capacity of short columns attributed to the lateral confinement of the concrete infill provided by the steel encasement. The …

Use of Material Tailoring to Improve Axial Load Capacity of Elliptical Composite Cylinders
This study focuses on the improvement of the axial buckling capacity of elliptical composite cylinders through the use of a circumferentially-varying lamination sequence. The concept of varying the lamination sequence around the circumference is considered as a viable approach for off-setting the …

Determination of axial load and support stiffness of continuous beams by vibration analysis
… on elastic supports, subjected to a compressive axial load. The first model, which approximates support stiffnesses by an equivalent elastic foundation, is found to be inaccurate for wave lengths close to the support spacing. A discrete mass model is formulated which accounts for axial load by …

Normal-strength and high-strength concrete columns under cyclic axial load and biaxial moment
… with and without CFRP jackets under constant axial load and variable lateral load. The lateral load was applied monotonically and cyclically. To predict the behavior of concrete columns under monotonic and cyclic compressive loadings, a computer code was developed to produce the …

Response of Wide Flange Steel Columns Subjected to Constant Axial Load and Lateral Blast Load
… wide flange steel columns subjected to constant axial loads and lateral blast loads was examined. The finite element program ABAQUS was used to model W8x40 sections with different slendernesses and boundary conditions. For the response calculations, a constant axial force was first applied to the …
