RESPONSE OF BUILDING COMPONENTS TO LAUNCH ACOUSTIC ENVIRONMENT

A computational procedure is presented for calculating the response of building components to acoustic loads due to spacecraft launch. The methodology described is in-built as routines into a software module “ACOUP” which forms part of the OSTA software package for off-shore and on-shore structural analysis using finite elements [1]. The software developed can be used to predict the acoustic response of any structure/structural component. One wall panel and one roof panel in each of the two buildings in launch acoustic environment at SHAR, INDIA and KSC, U.S.A. are analysed and the computed acoustic responses are compared with the responses measured at the respective places during the launches.
