Seismic performance evaluation of an airport traffic control tower through linear and nonlinear analysis

Abstract

Due to a lack of adequate information about seismic design and the performance of airport traffic control (ATC) towers, structural engineers often rely on building codes. However, seismic performance and the demands of ATC towers differ significantly from common structures. In this paper, the seismic performance of Kuala Lumpur International Airport traffic control tower, with a height of 120 m, was investigated. The results showed that in comparison to modal response spectrum analysis, equivalent static analysis overestimated overturning moments, drifts, maximum displacement and demand/capacity ratio. In addition, linear analysis underestimates base shear, drifts and overturning moments in comparison to the results of nonlinear time history and pushover analysis.
