ATTEC is local engineer for the Thornton Tomasetti’s Peer Review of the world tallest TV tower in Istanbul. Melike Altınışık Architects and Balkar Structural engineers are the Professionals-of-Record of the tower, 300 m tall, this tower is a 130 m stainless steel lattice antenna structure over a 170 m tall concrete base shaft. Lattice steel is 4.5 m wide in diameter tapering upwards, while the concrete shaft will be 15m in diameter at the bottom of the tower. Butresses are designed along the 8 underground podium levels connecting the shaft to the diaphragm walls for evenly distributing the foundation tension and the compression to the mat. Therefore, it is also minimizing tension anchorage requirements into the bedrock. The forms “bulging” from the concrete shaft will also be designed as composite construction with steel beams and inclined columns anchored to the shaft. Considered by the Municipality of Istanbul, an essential communications facility during and after an earthquake, the tower has been designed using non-linear performance based earthquake design requirements limiting it to very local plastic behavior even during the Maximum Considered Earthquake.
