Parametric Study of Time Period for RC Frame Structures with Infill walls.

Abstract

The seismic performance assessment of structures or buildings relies significantly on their time period, which is crucial for estimating lateral loads and evaluating seismic resistance. The time period is influenced not only by height and base dimensions but also by various other parameters. In this study, regression    analysis is used and explored different combinations of models considering height of the structure, thickness of infill, modulus of elasticity of infill and aspect ratio of the infill. Through this comprehensive approach, an equation is derived for the time period, aiming to achieve more accurate predictions to enhance the assessment of the structure's seismic performance. Lastly, analyses were done to compare the values of equation this study proposed with those from the IS code.
