This seminar presents the worked example of Section B4 of Examples of Concrete Structural Design to NZS 3101 (known as the Concrete NZ Red Book), demonstrating the design of a reinforced concrete diaphragm in a medium rise building. Major steps in the design process will be thoroughly explained, demonstrating compliance with NZS 3101:2006 Concrete Structure Standard and NZS 1170.5:2004 Structural Design Actions - Part 5: Earthquake Design Actions - New Zealand.
