Seismic Design
South Approach Viaduct is located so close to the activities during powerful earthquake for the first time in
world’s one of the most active seismic fault named as Turkey as Reinforcet Concrete Diaphragm Wall method.
North Anatolian Fault. This brings prequisite of serious
analysis on 3 different feedback perioded earthquake Viaduct is going to be protected from seismic threats with
scenarios like 150 years (FEE), 1000 years (SEE) and 2475 22 Lead Rubber Bearings, 108 Viscous Dampers (both
years (NCE). transverse and longitudinal) , 4 Spherical Bearings and 4
Steel pier foundations are designed for mitigation of fault Anti Uplift Devices.
Steel Pier and Deck
Manufacturing
South Approach Viaduct consisted of 11 piers between 10 - 50 meters height. Total weight of steel piers are
approximately 6.000 tons.
Decks are consisted of 16 subcomponents which have 40 meters length, 35,93 meters width and approximately 800 tons
weight as main components. South Approach Viaduct has 32 main components as deck parts. The sliding part of the
steel deck is composed of 16 sub-components and produced as 28 blocs weighing 800 tons and which are 35,93 m-wide,
40 m-long. The viaduct is built from 32 main constituents in total with the deck blocs added with the heavy lift method.
