Resumen

The objective of the research is to evaluate the seismic performance of the Diagrid structural system and the Dual structural system for important buildings in the city of Huancayo. The damage to these buildings caused by frequent seismic events is becoming an increasingly serious and recurring problem, with repairs becoming more and more expensive. In response to this problem, the implementation of new structural systems such as the Diagrid Structural System has been proposed for integration into Peruvian regulations, as these systems are known for their ability to combine structural efficiency with aesthetics. At the same time, this Diagrid System will be compared through a linear seismic analysis with the Dual System to demonstrate which one has better seismic performance according to the following indicators: Vibration Periods, Displacements, Inter-story drifts, Shear Force, Axial Force, and Bending Moment. It was concluded that the Diagrid Structural System performed better seismically than the Dual System, mainly because it reduced vibration periods by up to 50%, displacements by 46.85% and inter-story drifts by 40.54%.
