“…However, the MSLM material parameters have no physical meaning, because in complex structures a local spring stiffness is not measurable. Su and Wang coupled FEs with infinite elements to model plates of virtually infinite lengths and avoid reflection from boundaries [240]. Düster and Parvzian [69,192] introduced the finite cell method (FCM) and several extensions were presented by Schillinger et al [220].…”

This paper reviews the state-of-the-art in numerical wave propagation analysis. The main focus in that regard is on guided wave-based structural health monitoring (SHM) applications. A brief introduction to SHM and SHM-related problems is given, and various numerical methods are then discussed and assessed with respect to their capability of simulating guided wave propagation phenomena. A detailed evaluation of the following methods is compiled: (i) analytical methods, (ii) semi-analytical methods, (iii) the local interaction simulation approach (LISA), (iv) finite element methods (FEMs), and (v) miscellaneous methods such as mass–spring lattice models (MSLMs), boundary element methods (BEMs), and fictitious domain methods. In the framework of the FEM, both time and frequency domain approaches are covered, and the advantages of using high order shape functions are also examined.

“…Application of Infinite Elements to timedependent problems is typically performed in the frequency domain, producing solutions in terms of Hankel functions similar in many respects to the thin layer method, [92], [93], [94], and also requiring inverse transforms to produce a time-domain solution. Su and coworkers [95] have recently proposed a formulation where the static response of the infinite elements and the dynamic response of absorbing boundary conditions of the LK type are combined, in order to avoid the inverse transforms in the time domain required for the standard infinite element approach.…”

A generalized time-domain method for Soil-Structure Interaction Analysis is developed, based upon an extension of the Bielak Method. The methodology is combined with the use of a simple hysteretic soil model based upon the Ramberg-Osgood formulation and applied to a notional Small Modular Reactor. These benchmark results compare well with those obtained by using the industry-standard frequencydomain code SASSI. The methodology provides a path forward for investigation of other sources of nonlinearity, including those associated with the use of more physically-realistic material models incorporating pore-pressure effects, gap opening/closing, the effect of nonlinear structural elements, and 3D seismic inputs.

“…Damgaard et al [6], Lombardi et al [7], Bhattacharya et al [8] present various analyses for different types of projects where the importance of considering soil-structure interaction for the structural models studied was pointed out. Su and Wang [9] present a finite element model for a study with equivalent dynamic load considering the soilstructure interaction and Papadopoulos et al [10] present in their study the determination of the modal characteristics of structures considering the soil-structure interaction.…”

The influence of incremental constructive effects (IE) and soil-structure interaction (SSI) on high-rise buildings of reinforced concrete with shallow foundations on sandy soils were analyzed. IE and SSI evaluations were carried out by the parameters of global instability, maximum horizontal displacements, foundation loads, and settlements of a symmetrical and non-symmetrical plant of a 23-storey building For the analysis of the IE, the variation of the modulus of elasticity was considered over time along with the phases of application of loads in the building. For ISS analysis, the continuous medium was considered, and the calculation model considers a multi-spring-mass system under the foundation of the building. The results show a significant redistribution in the foundation efforts and suggest that a failure in considering these effects along with the structure can lead to projects that do not meet the standard specifications regarding stability parameters and overall structure displacements.
