DESIGN PHILOSOPHY The design of foundations is performed using In-House developed software. Load estimation is done with Dead load, Live load, Along wind load & Across wind load by both simplified method & Random method of analysis as per IS:4998 Part-1, IS:875 Part-3, IS:1893. Entire chimney above pilecap base is divided into 50 sections and forces like shear & Moments are calculated at each section. Lumped mass is modeled at CG of each section. Mode shape and frequency is determined for predominantly first two modes for across wind calculation in shell only case and shell + platform case. Resultant of alongwind and across wind is calculated at each section and compared with seismic load. Seismic analysis is done in STAAD Pro by Response spectrum method. Forces at each section is calculated and resultant worked out with dead load. This document covers load analysis for Pile layout and its design. Design of shell, platform etc. is covered in subsequent design documents.
