Modal analysis is a technique used to study the dynamic behavior of structures under various loads, such as earthquakes, wind, and other external excitations. It involves analyzing the structure’s response to these loads by decomposing it into its natural modes of vibration, also known as modes or eigenvectors. Each mode represents a specific pattern of vibration that the structure can undergo, and the frequency at which it vibrates is called the natural frequency.
ETABS (Extended Three-Dimensional Analysis of Building Systems) is a powerful software tool used for structural analysis and design of buildings and other structures. One of the key features of ETABS is its ability to perform modal analysis, which is a crucial step in understanding the dynamic behavior of structures under various loads. In this article, we will provide an in-depth look at ETABS modal analysis, its importance, and how to perform it. etabs modal analysis
