“…The applications of tsunami forces on structures are thoroughly investigated in the past through physical modelling and experimental-based research. An experimental research was conducted to test the effect of tsunami forces on a storage tank, whereby two conditions were considered which are with and without surrounding tanks [13]. A wave basin with dimension of 30m in length, 19m of width, and a depth of 1.5m was used in the experimental study.…”

This paper reviews methods applicable to assess the impact of tsunami forces on coastal structures. Countries affected by tsunamis have proven that this environmental disaster has costed billions of losses, such as the event occurred during year 2004 Andaman tsunami. Therefore, there is a need to assess the structural behaviour upon the impact of tsunami forces in order to minimize the damages and to ensure that coastal structures are able to sustain loading from high current-velocity waves. Currently in practice, there are two approaches of accessing the impacts of tsunami on structures namely physical modelling and experiment or numerical modelling and simulation. Numerical modelling methods are expected to produce acceptable analysis on the stability and condition of structures subjected to tsunami loadings since it incorporates several important parameters which are not implemented in physical modelling. The result from this study is expected to prompt engineers and relevant authorities to revise the current design guidelines on coastal structures which could sustain possible tsunami event in the future.

“…Furthermore, most of the previous researches, including the experimental studies and model predictions, have relied on high-frequency cyclic loadings, such as seismic loading and traffic loading [3,8,14]. However, no much effort has been done to investigate the deformation characteristics of soft marine soil tested under cyclic loading with low frequency, such as the tide, repeated changes in storage structure levels, and even periodic draining and recharging of the groundwater [31,32]. us, in this work, triaxial shear tests were conducted under cyclic loading with different low frequencies on soft marine soil.…”

Soft marine soil which could be found widely at the coastal and offshore areas is usually associated with high settlement and instability, especially under cyclic loading. Many research studies have been conducted on its deformation characteristics under the cyclic loading with high frequency, whereas few works have been reported on that under the low-frequency cyclic loading which largely existed in engineering. In this work, a comprehensive series of undrained triaxial tests under cyclic loading with low frequency was conducted to investigate the deformation characteristics of soft marine soil. The results demonstrate that soil specimens accumulate plastic deformation and pore pressure under cyclic loading. Specimens tested under conditions such as high confining stress, high-stress ratio, and long cyclic period generally reveal higher deformation and pore pressure. Meanwhile, the rectangular wave presents the largest contribution to plastic strain and pore pressure, followed by the trapezoidal and triangular waves, respectively, whereas the difference between the various waves decreased gradually with the increasing load level and cyclic period. The undisturbed specimens displayed lower deformations and pore pressures than the reconstructed specimens, whereas the differences are not significant when the confining stress is much higher than the structural yield stress. Furthermore, an empirical model for predicting the evolution of pore pressure is proposed and then validated against the experimental data in both this work and the literature.

“…The threats deriving from NaTech scenarios have long been recognized and investigated in chemical and process plants (Young et al, 2004;Godoy, 2007;Cruz and Okada, 2008;Antonioni et al, 2009;Cozzani et al, 2010;Krausmann et al, 2011;Cozzani et al, 2014;Marzo et al, 2015, Krasumann et al, 2017. Accordingly, many techniques have been developed for quantitative risk assessment and management of NaTech events triggered by floods (Haptmanns, 2010;Landucci et al, 2012;Antonioni et al, 2015;Khakzad and van Gelder, 2018;Kameshwar and Padgett, 2018), by lightning (Necci et al, 2013;Necci et al, 2016;Wei et al, 2018), by tsunami (Mebarki et al, 2016;Araki et al, 2017;Nishino and Imazu, 2018), by earthquakes (Salzano et al, 2003;Fabbrocino et al, 2005;Antonioni et al, 2007;Campedel et al, 2008) and by wildfires were developed.…”
