THE EFFECTS OF THE EARTHQUAKE INCIDENT ANGLE ON AN RC BUILDING

Abstract

Current building codes necessitate the inclusion of two ground motion acceleration components in the dynamic analysis of structures. However, researches indicate that the orientation of the chosen ground motion data can significantly impact the structural response. This study investigates the influence of the incident angle on a 10-story reinforced concrete building, considering different earthquake selection criteria. Specifically, it is aimed to identify the direction of the seismic data that yields the largest peak ground acceleration by applying rotations with specific angles. Subsequently, the dynamic analysis is performed using both the original and the rotated records that produce the highest acceleration. To ensure a comprehensive evaluation, the earthquake data is classified based on soil types, fault mechanisms, and Aria’s intensity. The results of the dynamic analyses for both the original and oriented data sets are compared, focusing on parameters such as roof displacement, base shear, acceleration and displacement time histories, and acceleration and displacement spectra. Our findings reveal that the base shear and roof displacement obtained from the rotated earthquake data generally exceed those obtained from the original data. This underscores the importance of considering the influence of ground motion direction in structural analysis and design.
