Jrw501 structural 19 jul 11 08 16 this is a pretty simple question and like most people here i d suggest speaking with a mentor but i m sure a lot of things i d ask would be considered simple by most people on this forum. We recommended this type of pile in battered situations. The piles consist of thick walled steel tubes which are filled with concrete and composite characteristics are allowed for in their design. Your additional stiffness can be quantified by ei effective equation i2 14 of aisc 13th pg.
If a concrete. Pipe piles can be driven either open ended or closed ended. It is considered that the local buckling strength of steel piles with concrete at. In case of closed end piles the driving end of each piling pipe is closed by welding a bottom steel conical steel or cast iron rock shoe to the pipe end.
Pipe piles can be filled with concrete to provide additional capacities or corrosion protection. I ve used concrete filled pipe piles a few times on marine structures for the purpose of decreasing deflections. Two types of strain gages resistive and vibrating wire were mounted to the steel pipe pile and checked by determining the known young s modulus of steel e. The joining of the large diameter piles is normally made by welding.
A steel pipe pile section filled with concrete was instrumented and tested under axial load. 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. Either the open ended or the close ended pipes pile can be driven. Usually the money spent on plates rebar and concrete would be better spent on a larger thicker pile.
Reinforcement is not normally used in small diameter cfsp piles. In most cases pipe piles are filled with concrete. In some cases pipe piles are not filled with concrete to reduce the cost. If driven with plates the pipes can then be filled with concrete to add strength to the pile.
If pipe piles were not filled with concrete then corrosion protection layer should be applied. Steel pipe piles and steel pipe sheet piles are widely used in ports harbors piers seawalls and breakwaters urban civil engineering earth retaining walls and cofferdams bridges foundations for steel pipe sheet pile foundations and other applications along with widening their applications due to enlargement of the structures sizes growth of water depth for the structures and increase in construction work at sites where the bearing strata are deep under thick soft ground.
