A world trade center puts together under one roof all the services associated with global commerce, a kind of shopping mall providing networking access between corporations and governments. A WTC address gives a business prime and continuous access and exposure to all the services, organizations and individuals essential for success in world trade. "A World Trade Center in any city is a business shopping center, complementing and supporting the existing services of private and government agencies", explains World Trade Center Association (WTCA) President, Guy F. Tozzoli.
The World Trade Centers Association founded in 1970 and based in New York City, is an organization of nearly 300 world trade centers in almost 100 countries. The WTCA is an unofficial umbrella trade association that brings together corporations and government agencies involved in international trade.
In addition there are other buildings around the world known by the title such as in Hong Kong: see World Trade Centre
The WorldTradeCenter in New York City (sometimes informally referred to as the WTC or the Twin Towers) was a complex of seven buildings, mostly designed by Japanese American architect Minoru Yamasaki and developed by the Port Authority of New York and New Jersey.
The 208 feet (63.4 m) wide facade was, in effect, a prefabricated steel lattice, with columns on 39 inch (100 cm) centers acting as wind bracing to resist all overturning forces; the central core took the majority of the gravity loads of the building.
Later that day, 7 WorldTradeCenter also collapsed, while the four remaining buildings in the WTC plaza also sustained heavy damage from debris and were ultimately demolished.
