Hi am Deepthi, i would like to get a detailed report on the diagrid system which should brief about the evolution of the diagrid system and also the detailed report on its significance as an innovative, sustainable, and efficient structural system.

The diagrid structural system can be defined as a diagonal member formed as a frame formed by the intersection of different materials such as metals, concrete or wooden beams used in the construction of buildings and roofs. The diagrid structures of the steel members are efficient in providing solution both in terms of strength and stiffness. But today a wide application of diagrid is used in buildings of great span and height, especially when it comes to complex geometries and curved shapes.
The diagrid (an acronym for diagonal grid) is a frame of diagonally crossed metal, concrete or wood beams that is used in the construction of buildings and roofs. It requires less structural steel than a conventional steel frame. Hearst Tower in New York City, designed by Norman, Lord Foster, uses 21 percent less steel than a standard design. The diagrid eliminates the need for columns and can be used to make large extensions of roofs without columns. Another iconic building designed by Lord Foster, 30 St Mary Ax, known as "The Gherkin", also uses the diagrid system.
