Effect of the pile cap length and the soil relative density on the pile cap – pile – dense soil interaction: Experimental investigation

Case Studies in Construction Materials
In the present study, the RC pile cap-pile-soil interaction was experimentally investigated by testing twelve half-scale RC pile caps. Two main parameters were considered within the experimental program; the first factor was the relative density of the ...

Suggestion of ultimate strength formulas of partial frame pile cap composed of exterior column, foundation beam and pile

Acta Polytechnica CTU Proceedings, 2022
Currently, there is no research and few valid experiments of pile caps. And shear failure mechanism of a pile, exterior column and foundation beam and pile caps in RC structure is not resolved yet under bi-lateral loading.
