Assessing the Seismic Demands on Non-Structural Components Attached to Reinforced Concrete Frames

Nonstructural components (NSCs) are the systems that attached to floors of a building structure. NSCs have become critical in sustaining post-earthquake functionality while constructing seismic-resilient structures. The seismic behavior primarily depends upon structure which NSC is attached. Building structures subjected earthquake loads and behave differently when supporting soil type varies. In light this, this study investigates demands on an elastic-reinforced concrete frame supported by different types. present considered regular with mass irregularity lower story. A total 3 sets 11 horizontal spectral-matched ground motions consistent each considered. Floor response spectra (FRS) can be used measure load non-structural components. Primarily, it was found ordinates FRS depend floor height, vibration periods building, type. presence at story amplified all levels. Additionally, values spectral acceleration increase as flexibility increases. amplification factors for generating spectra, their variation along height discussed. vary non-linearly building. Finally, artificial neural networks (ANNs) employed develop prediction models dynamic factors. results calculated time history analyses utilized validate proposed models.
