Effects of Various Bracing Angles on Steel Diagrid Building: An Analytical Approach
Mridul Rawat,  Ankush Kumar Jain
Three models were prepared with identical floor plans, geometry and other properties except braces and columns at exoskeleton and inner area. These models were studied for different bracing angles as 55 degree, 60 degree and 65 degrees. Analysis performed using Autocad and STAAD Pro software. Obtained results showed that model having lower angle are good against wind pressure however model with higher angles are good against seismic forces as base shear. Model with 60 degree angle performed best against storey displacements & moderately good for seismic base shear. One of the reasons that model with 60 degree angle performed best was 60 degree angle formed geometry close to equilateral triangle formation for distributing loads more evenly when subjected to lateral loading. It is also found a threshold limit at 57th storey regardless of bracing angle of model. Similar values were received for all models and overlap with allowable limit at that height.
Keywords- Steel Diagrid, Storey Displacement, Variable Bracing Angles.
