In this paper, we investigate the seismic response of 2D building subjected to harmonic sinusoidal forces at the base with varying frequencies. Linear time history analysis (LTHA) is employed to evaluate the dynamic behavior of 2-story 4-bays reinforced concrete (RC) shear frame to capture the structural response across resonance conditions.
To ensure an accurate assessment of vibration responses, both analytical methods (Modal analysis and Duhamel integration) and numerical approaches (Newmark Beta and Wilson Theta) are employed. Additionally, Finite Element Analysis (FEA) is performed using the SAP2000 software to compare the results. The study reveals that the excitation frequency significantly influences displacement and interstory drift responses. High-frequency excitation does not produce large displacements of the floors.
This work highlights the importance of considering both excitation characteristics and structural properties in seismic design, and it emphasizes the significance of integration analytical and numerical methods in modern seismic engineering practices.
Key words: RC frame / harmonic force / time history analysis
