Seismic Performance Evaluation of a 10-Story Structural Wall Building under Severe Earthquakes in Lima, 2025

Abstract

This research aims to contribute to the study of seismic behaviour by evaluating the seismic performance of reinforced concrete wall structures through the development of a representative archetype. This archetype was elaborated based on the analysis and systematisation of ten structural plans of real buildings that share similar characteristics. The methodology followed includes the non-linear static analysis to determine the data that will help to plot the capacity curve of the structure. This process is carried out with the Stera 3D software that provides the data of the capacity curve, then the demand curves or demand spectra are elaborated according to the indications of the vision 2000 committee. Subsequently, the structural performance point is determined through the intersection between the capacity curve and the demand curves, which makes it possible to identify the level of performance achieved. The results obtained show that the archetype analysed achieves a different performance level for each earthquake that generates a different demand curve. This approach allows a more accurate understanding of the seismic behaviour of similar buildings, providing useful tools for decision making in structural design and seismic strengthening.
