Investigation into Earthquake of Buildings with Mass Imbalance

Puntos clave

Structures with mass irregularities showed significantly higher base shear values than regular configurations.
Peak storey shear forces were primarily concentrated at lower storeys and base levels of buildings.
Response Spectrum Analysis and Pushover Analysis were employed to assess seismic behavior and resilience.
Findings indicate a greater demand on lateral load resistance for buildings with vertical irregularities.

Resumen

This research focuses on examining how different forms of vertical irregularities influence the seismic performance of reinforced concrete (RC) structures. The main objective is to conduct both Response Spectrum Analysis (RSA) and Pushover Analysis on RC building frames exhibiting vertical irregularities, and to compare their seismic behavior with that of regular configurations. The study specifically considers mass irregularities and other forms of vertical discontinuities. It was observed that the storey shear force reaches its peak at the lower storeys, particularly at the base, and progressively reduces in the upper levels. Notably, structures with mass irregularities exhibited higher base shear values compared to their regular counterparts, indicating a greater demand on lateral load resistance.
