Abstract
Turbo Generator Frame Foundation is very important for all types of power plants viz. Gas, Steam, Hydro, Geothermal and nuclear Power Plants.The turbo-generator is the main part of a power plant. Turbo-generator is generally mounted on the top deck of the foundation. In this work, Structure Interaction (SBSI) has been studied by conducting experiments and numerical analysis in SAP; 2000 software. A Barrette is a cast-in-place reinforced concrete column. The role of the Soil-Barrette-Structure Interaction (SBSI) is advantageous to the Turbo-Generator Foundation system under seismic loading because it transfers seismic loading through columns to Barrettes Experimental tests have been conducted for three different cases, namely: (i )Turbo Generator Foundation supported by Raft on medium dense sand, (ii) Turbo Generator Foundation supported by pile in medium dense sand, (iii) Turbo Generator Foundation supported by Barrettes in medium dense sand. In addition to the experiments, SAP; 2000 has been used for comparison of results of above three cases. Results are plotted in terms of the structural response parameters such as Displacement in Top deck at seismic loading places, comparison of frequency and acceleration. Comparison of the numerical results and the experimental data shows a good agreement confirming the reliability of the numerical model. Both experimental and numerical results reveals that Soil-Barrette-Structure Interaction decreases displacement of top deck at lateral direction and frequency comparison to raft and pile structures
