Recent Advancements, Trends and Future Paradigms in Structural Design of Reinforced Concrete (RC) Tall Buildings Naveed Anwar, PhD Why new paradigms and needed? How long do we have before the building will collapse din this fire? - Asks the Fire Chief from the structural engineer / (Architect) 1974 Concrete Asia 2016 Naveed Anwar, AIT 3 The Towering Inferno (1974) https://www.youtube.com/watch?v=FagbC09BO2o Concrete Asia 2016 Naveed Anwar, AIT 4 The Challenges • Architectural Design and Structural Engineering • Bigger, taller, complex forms, but Lighter, smaller, thinner structural elements • High performance, but Lower cost • Architects and Structural Engineers • Apparent lack of innovativeness • Difficulties in collaborative working Concrete Asia 2016 Naveed Anwar, AIT 5 Percentage of Urbanized World Concrete Asia 2016 Naveed Anwar, AIT 6 World’s Population Urban-to-Rural Ratio (www.un.org) Concrete Asia 2016 Naveed Anwar, AIT 7 Urbanization → Growing Needs for built-up space Concrete Asia 2016 Naveed Anwar, AIT 8 The Case of London Concrete Asia 2016 Naveed Anwar, AIT 9 Advise to my fellow Engineers 1. Design is a team effort, and Architect is the lead 2. Everything is possible, don’t say no! • but it needs innovation, knowledge, skills, tools and, • of course resources 3. - - - Concrete Asia 2016 Naveed Anwar, AIT
