Concrete Footings with Different Socket Shapes Subjected to the Axial Compressive Load

Abstract

These paper concrete footings with pyramid ended sockets are discussed in comparison to the typical socket foundation constructions. Discussed connection with cut-off pyramid creates opportunity to reduce the required height of foundation in comparison to the typical solutions and leads to reduced weight as well as costs of foundation casting. Comparative analysis covered three different external shapes for both foundations (with normal and pyramid ended socket) i.e. prism, stepped and sloped. The subject of interest was if and how much the height of foundation could be reduced in comparison to the normal socket footing. Numerical analysis was performed with the utilization of SolidWorks Finite Element Method based software.
