Abstract

The profound impact of earthquakes on human lives and the built environment emphasizes the substantial human and economic losses result-ing from structural collapses. Many researchers in this field highlight the longstanding societal challenge posed by earthquakes and under-score the imperative to minimize such losses. Over the decades, researchers have dedicated efforts to seismic design, focusing on improv-ing structural performance to mitigate earthquake-induced damages. This has led to the development of various structural analysis methods. In this research, a specific RC frame structure (401 Bldg.) at Kyungpook National University that is designed for educational purposes, serves as a representative case. This research employs SAP 2000 for simulation, aiming to assess the structural performance under seismic condi-tions, focusing on evaluating the structural behavior under different column orientations. This research utilizes RSA (Response Spectrum Analysis) to comprehensively examine parameters of displacement, base shear force, base moment, joint radians, and story drift. Referring to the results from RSA, this research also assesses the structural performance using LTHA (Linear Time History Analysis) by conducting synthetic frequency domain and synthetic time domain analyses based on the seismic wave from the Kobe 1995 earthquake (Abeno). Based on the findings from the discussions, this research is expected to be a valuable reference for structural design within seismic resistance and the seismic reinforcement of existing RC frame structures.
