For real structures, concrete is filled into the pile top of steel piles to fix the connection between a steel pile and a reinforced concrete footing beam in. It is considered that the local buckling strength of steel piles with concrete at the pile top is larger than that of steel piles ...

piles can be driven with open or closed ends, with points or plates. If driven with plates, the pipes can then be filled with rebar and concrete to boost the strength to the pile. Pipe piles range in size from several millimetres to several metres in diameter and can be easily spliced ...

Pretensioned spun high-strength concrete (PHC) piles have been widely used in building foundations in many parts of the world. However, PHC piles are also known to have poor lateral deformation and ductility capacity and hence are not suitable for seismic regions. To improve the horizontal load ...
This paper reports and experimental investigation in which the effects of fibre volume fraction and the ratio of unloaded to loaded area on the ultimate bearing capacity of concrete are studied. Two types of loading patterns, namely, concentric and edge loading were adopted. A simple theoretical mo...
