Seismic Evaluation and Retrofit of the Ataturk International Airport Terminal Building

Abstract

MCEER was part of a team charged with the seismic upgrade of Istanbul's Ataturk International Airport Terminal Building. The project involved analysis of post-earthquake damage to the Terminal Building following the 1999 Marmara, Turkey earthquake, and development of a retrofit scheme. Nonlinear static and dynamic analyses were conducted using procedures set forth in FEMA 273 (including numerous contributions from MCEER researchers). Pushover analyses were conducted using IDARC (developed with MCEER support). Dynamic analyses of the roof-isolated structure considering inelastic frame behavior were conducted using computer software based on modifications of program 3D-BASIS (developed with MCEER support). Several retrofit schemes were investigated, including conventional methods and materials, and new technologies. The scheme selected included isolation of the roof trusses, addition of shock transmission units, and selected retrofit and strengthening of reinforced concrete construction. The Turkish build-operate-transfer consortium, TEPE-AKFEN-VIE (TAV) and its advisor, New York-based Turner International, approved the evaluation and retrofit scheme. Members of the team were LZA Technology, a division of Thor nton-Tomasetti Group (leader), Michael C. Constantinou and Andrew S. Whittaker (formerly of PEER), both of the University at Buffalo, and Tuncel Engineering and Fondsiyuon Muhendislik Insaatvetic Ltd., both of Istanbul. The project is an excellent example of bringing research results to implementation.

Study on Column-Top Seismic Isolation of Single-Layer Latticed Domes

“…Lead has good fatigue resistance for the plastic cycling load, and high-purity Pb (99.99%) is easy to obtain, which makes its mechanical properties more reliable. This article selects the Fuyo lead rubber bearing series product LRB600, produced by the Wuxi construction new material Limited Company [9]. Its mechanical performance parameters are shown in Table 1.…”

Seismic behavior of steel space truss connections to reinforced concrete supporting columns

“…The new three-story terminal building at the Ataturk International Airport was damaged during the 1999 Izmit earthquake. The damage, including loss of concrete at the underside of the roof truss-cantilever column connections, slippage of the roof truss base plates atop the columns, and splitting cracks and spalled concrete in the beam-column joints at the top of columns, were observed (Constantinou et al, 2001). Similar observations have been reported in the Great East Japan Earthquake of 2011 in Japan (AIJ, 2014; Matsumoto et al, 2012) and Lushan Earthquake of 2013 in China (Dai et al, 2013; Li et al, 2019).…”

Shaking table tests on spherical sliding bearings taking eccentricity and uplift into account

“…The SSB can determine its natural period irrespective of the supporting weight and can adjust the maximum deformation because of the concave‐plate curvature, which is difficult for laminated rubber bearings, especially in lightweight structures. Therefore, SSBs are suitable for seismically isolated roofs or lightweight housings, which have been employed to support the roof structures of airports or the terminal buildings themselves for seismic isolation…”
