Seismic fragility analysis of a pile-supported wharf using capacity spectrum method

Seismic Vulnerability Assessment of Critical Port Infrastructure Components by Modelling the Soil-Wharf-Crane Interaction

“…Figure 11 compares the wharf structure damage estimations obtained using the method developed in this study with those obtained by the methods available in the literature for the chosen scenario earthquake. The models included in the comparison are the fragility model developed by Shah (2020) [3] for pile-supported wharves in Indian ports, and the fragility models developed by Yang et al, (2012) [5] and Su et al, (2019) [10] for piled-wharves in United States ports. The close agreement between the present study results and those obtained by the Shah deserves special attention.…”

“…5,2475 was found to be 0.325 g amplified at the soil surface as F β S 1 . 5,2475 = 0.625 g. The models included in the comparison are the fragility model developed by Shah (2020) [3] for pile-supported wharves in Indian ports, and the fragility models developed by Yang et al, (2012) [5] and Su et al, (2019) [10] for piled-wharves in United States ports. The close agreement between the present study results and those obtained by the Shah deserves special attention.…”

“…HAZUS (NIBS, 2004 [18]) proposed empirical fragility curves for waterfront structures (without distinction between different wharf typologies) and the cargo handling equipment. With specific reference to pile-supported wharves, analytical fragility functions based on the outcomes from the numerical analysis were developed by different authors, such as Na et al, (2009) [19], Shafieezadeh (2011) [20], Thomopoulos and Lai (2012) [21], Yang et al, (2012) [5], Mirfattah (2013) [22], Heidary-Torkamani et al, (2013) [23], Bozzoni et al, (2014) [24], Ntritsos (2015) [25], Su et al, (2019) [10], Shah (2020) [3], and Mirzaeefard et al, (2021) [26]. Kosbab (2010) [27] and Tran et al, (2019) [28] proposed analytical fragility curves for container cranes.…”
