“…It is important to note that the installation of these instruments requires detailed planning of their location, such as the one carried out on the Tauranga Harbor Link bridge (Ibrahim et al, 2008). For periodic measurement of deflections in this method, laser equipment such as LDV (Laser Doppler Vibrometer), photogrammetry, or microwave radars have been used (Board et al, 2005;Gentile & Bernardini, 2010;Ja et al, 2003;McCarthy et al, 2014). However, in some cases, such approaches lack the necessary precision and generate errors in the measurement (Helmi et al, 2015;Moschas & Stiros, 2013;Roberts et al, 2004;Watson et al, 2007;Yi et al, 2011).…”
