Abstract

En 中文

With a world record in main span length of 2023 m, the 1915 & Ccedil;anakkale Bridge is located at the north-eastern end of the & Ccedil;anakkale Strait in T & uuml;rkiye which has the heaviest navigation traffic and severe windy conditions. The planning, design and construction of the bridge having the design life of 100 years raised various technical challenges against extreme loadings such as live loads on long span, strong wind, earthquake and even ship collision. To define the design loads, geological investigation, geophysical study, meteorological study and traffic study were thoroughly progressed at the beginning stage of design. The ultimate challenge was to complete the project within only 5 years. The detailed design process had to be efficient and firmly optimized to allow for fast construction. Significant design challenges for aerodynamics, ship collision, seismic and poor soil conditions had to be managed. Various three-dimensional global analysis models including detailed local models based on the most advanced Finite Element Model technology were developed to overcome strong wind, earthquake and ship collision. Then, the design was verified by wind tunnel test and simulations. Also, the project had been proceeded by fast-track construction to accelerate the opening, and efficient fabrication and installation methods were adopted.
