Elastic analysis mode in the PileGroup program
In this analysis mode, the approximate closed form solutions for single piles subject to axial loading (Randolph and Wroth 1978a and 1978b)
Innovative Geotechnics is an engineering company with the aim of researching and developing geotechnical design and analysis programs.
Innovative Geotechnics provides innovative geotechnical design tools for soil-structure interaction and deep foundation problems such as single piles or pile groups under lateral and vertical loads.
Single Piles and Pile Groups
Innovative Geotechnics provide geotechnical design tools for soil-structure interaction problems such as pile groups, laterally loaded piles, nonlinear p-y curve generation, and rock socket design, including single piles or pile groups under lateral and vertical loading based on finite element method. Our programs are focused on the geotechnical analytical knowledge, improving user engagement, and reducing potential input uncertainties. All geotechnical programs and software adopt simple input interfaces for the users to interactively enter the analysis information such as soil layer information, soil properties, and foundation design parameters.
