Analysis of Earthquake-Resistant Behavior in Buildings with the Implementation of the Metal Structural System of Rigid Perimeter Grid

The current research is focused on the application of the rigid grid steel system, known as Diagrid, in tall buildings for the analysis of their seismic behavior to demonstrate the potential benefits that this could perform, to be applied in lands located in seismic zones “4”, such as Lima Metropolitan. This investigation aims to determine how the Diagrid system influences the seismic performance of buildings. Hence, data collected from five previous research compared the number of stories and the inclination angle of each grid based on the technical specifications and international requirements for earthquake-resistance design. Through the results obtained, it will be able to quantify the seismic behavior of the buildings. For instance, the top stories displacements increased by around 20% for each story increased, and by 10% for each inclination angle. To recapitulate, each structural element of the Diagrid system plays a significant role in seismic behavior bringing more ductility to the structure and, in consequence, inhibiting further structural damage. The number of floors directly influences the inclination angle; the taller the building is, the greater the inclination angle of the grids is. And consequently, the inclination angle is a determining parameter for the seismic behavior of tall buildings.
