Dear Colleagues, Turkish Constructional Steelwork Association (TUCSA) is organizing the 8 th International Symposium on Steel Bridges: Innovation & New Challenges 2015 (SBIC-2015) which will be held in Ã„Â°stanbul between 14 th and 16 th September 2015 in coordination with European Convention for Constructional Steelwork (ECCS) in conjunction with the ECCS Steel Design Awards Ceremony and ECCS Annual General Meetings. About in the middle of the 18 th century bridge construction began to assume a more scientific aspect than before. Production of iron and steel in commercial scale gave new possibilities. Seemingly the most recent century will be the age of structures considering steel of prime importance. Main motive of the Symposium is that there is still much to do to develop and promote steel in construction industry. Istanbul is one of the best places to organise the bridge symposium which is a natural bridge between Europe and Asia in addition to having three steel bridges over Bosphorous. This event will give us the opportunity and mission to organize and announce a symposium for architects, structural engineers, designers, steel fabricators and builders as well as environmental psychologists, urban planners and environmentalists to discuss new horizons on steel bridges. We hope to be together with you in Istanbul.
