Review paper on Diagrid and Hexagrid structures

Abstract

Out of the many feats of engineering in the twenty-first century the modern skyscraper is the most noticeable in the city architecture yet one of the least appreciated one. In the constantly evolving and expanding urban world the skyscrapers and the high rise in general helps to deal with many problems such as the accommodation of many different amenities in the same place and the optimum utilization of the precious resource in cities which is land. However, this engineering marvel comes with its own set of problems and challenges for the engineers with regards to its serviceability and safety criterion. As the height of the structure increases the lateral forces namely the earthquake and wind forces become more critical. To tackle these problems different structural systems are used such as Rigid frame, Shear wall, Outrigger structure, Tube system, Diagrid system, Pentagrid system and Hexagrid system. The two systems extensively researched and used now a days are Diagrid and Hexagrid systems.
