Abstract: Humanity has an obsession for high rise structure. In the 20th century the focus was on strength, rigidity, massive structural members like the Empire State Building. However, in 21st century structural engineers are looking for innovative structural designs for tall building. Various techniques like Tubular system, tube in tube, outrigger with belt truss, diagrid structural system have led to decrease in size of structural members. The objective of this Research paper is to look for optimum design for high rise building. For this purpose a typical building plan with same loading cases is analyzed for 7 different structural configurations. All the models are satisfying structural codes – IS 456-2000, IS 1893 – 2002, 2016, IS 132920, IS 875, NBC- 2016. The dead load on structure on the structure is reduced by use of innovative aerocon partition panels. Thus leading to optimization of the structure. The structural performance of Moment Frame, Moment frame with Shear wall at corners, Moment frame with Core Tubular, Tube in Tube Structure System, Outrigger Structure System, Outrigger with belt truss structure system have been compared at the end with parameters Base shear, storey response, Time period. Dynamic analysis has also been performed on all model.
Keyword: Optimum Structural design, Moment Frame, Moment frame with Shear wall at corners, Moment frame with Core, Tubular, Tube in Tube Structure System, Outrigger Structure System, Outrigger with belt truss structure system.
Scope of the Article: Design and Performance of Green Building.
