Design optimisation of reinforced concrete pile foundation using generalised reduced gradient algorithm

Purpose The purpose of this study is to find the optimum design Reinforced Concrete (RC) pile foundation enable efficient use structural concrete with greater consequences for global environment and economy. Design/methodology/approach A non-linear optimisation technique based on Generalised Reduced Gradient (GRG) algorithm was implemented minimum cost RC in frictional soil. This achieved by obtaining satisfying serviceability ultimate limit state requirements BS 8004 EC 7. formulated procedure applied a case project assess efficiency proposed formulation. Findings results prove that GRG method Excel solver an active, fast, accurate computer programme obtain design. application shows up 26% reduction compared conventional Research limitations/implications formulation constraints will be limited provisions Practical implications Since quantity attained through optimisation, then cement used thus result CO 2 emission. Therefore, structures vital solution damage Earth's climate physical resulting from high carbon emissions. Originality/value current considers incorporation different soil ground parameters process rather than assuming any capacity value process.
