Modal Analysis is a common practice to define parameters of structure under scientific view. The properties that come along need to be enlightened so that every circumstance appeared may be tackled in proper manner. Experimental Modal Analysis (EMA) is a well-known procedure for determining modal parameters. The EMA is regarded as an ‘indoor tools’ to examine modal parameters. Meanwhile, Operational Modal Analysis (OMA) on the other hand acts as an ‘outdoor tools’, or operated at site. Here, the EMA analysis method will be discussed. Modal parameters consist of mode shape, natural frequency and damping ratio.
