Diagrid seminar report, abstract

Diagrid, an introduction
Now days, the building is created with steel in the form of a triangle with diagonal support beams. These structures are called diagrid. The main advantage is that, it requires less steel as compared to other normal structures. Hearst tower is a perfect example of diagrid structure. In these structures, you do not need large corner columns. The main advantage is that the load is uniformly distributed. It is believed that the diagrid structure was introduced by Vladimir Shukhov. It works on the principle of biomimicking. It is characterized by a perimeter structural. The diagonal members are present in gravity and lateral load resistance.

Thus it provides lots of strength to the structure. Shear and moment is present in the diagonals. The height of the building determines the optimal angle of the diagonals. The optimal angle for columns is around 90 degrees and for diagonals with maximum shear is 35 degrees. For diagrid structures, optimal angle lies between these two values. The optimal angle may increase as the height increases. It is generally in the range of the 60 to 70 degrees. Diagrid structures have applications in the buildings with complex geometry and curved shapes. The triangular shape that is constructed is generally an isosceles triangle.
