Abstract

The development of tall buildings was made possible by developments in structural systems, materials, construction technology, and analytical techniques for design and analysis. Lateral loads from wind and earthquakes have an impact on the structural construction of high-rise buildings structure’s lateral load resistance may be supplied by external or internal systems. Shear wall cores, braced frames, and combinations of these with frames are examples of interior structures that can withstand lateral loads. Contrarily, framed tubes are unable to withstand lateral loads from components situated outside the building’s perimeter, whereas braced tubes are. Selecting the right structural system is crucial to making effective use of the structural elements while meeting design specifications. The diagrid structural system, which has become more and more common in tall structures because of its architectural flexibility and structural efficiency, has slanted columns on the outside of the building rather than the vertically aligned columns that are typical of framed tubes. The inclined columns of this design aid in lateral load resistance. The diagonals’ axial movement in a framed tube structure resists stresses more effectively than the vertical columns’ bending. Since the surrounding diagonals can withstand lateral shear, diagonal buildings usually don’t need a core. The design and analysis of a 36-story diagrid steel skyscraper with a conventional 36 m x 36 m floor plan are presented in this paper. The structural components, which are constructed in accordance with IS 800:2007, are modelled and analysed using ETABS software, which accounts for all potential load combinations. The design and evaluation of the structure take into account dynamic elements associated with both wind directions. This 36-story skyscraper’s diagrid system’s load distribution is also examined. Additionally, 36-story diagrid construction analyses and plans are finished. The analytical results are compared in this work according to time period, displacement at the top storey, and inter-storey drift.
