Article
Serviceability criteria for offshore monopiles include the estimation of long-term, permanent tilt under repeated operational loads. In the lack of well-established analysis methods, experimental and numerical research has been carried out in the last decade to support the fundamental understanding of monopile–soil interaction mechanisms, and the c...
Article
The present work extends the capabilities of the Particle Finite Element Method (PFEM), which allows modeling of soil-fluid-structure interaction problems, to allow the modeling of sediment transport and scouring effects. This is accomplished by implementing scouring rules on an evolving scourable-interface, i.e. the interface surface between fluid...

ShakerMaker is an open-source python framework which simplifies the generation of synthetic broad-band seismograms, produced by finite-fault kinematic representations of earthquake ruptures, using a 1-D layered model of the crust and the frequency–wavenumber (f–k) method. It is designed to bring closer the engineering seismology and earthquake engi...
Article
The modeling of structural damping due to the excitation of elastic-waves into the surrounding soil domain, and its effect on structural response as apparent modal damping is explored herein. Four high-fidelity, linear finite-element models of building-site systems, with 20–50 storeys and 2–7 basement levels, are simulated in OpenSees to evaluate t...
Chapter
This paper presents a method to update linear time-variant finite element (FE) models of civil structures experiencing nonlinear behavior due to earthquake excitation. First, the time-varying modal parameters of the structure are identified using the input–output dynamic data recorded during a damaging seismic event by employing a short-time window...
Article
In this paper, we employ a Bayesian approach to estimate the parameters of a high cycle accumulation model for sands using experimental data. Global sensitivity analysis and Markov-Chain Monte Carlo simulation are conducted for each of the twenty-four available experimental drained triaxial test results, considering the effect of estimating soil pa...
Article
The need to build tall buildings has been increasing worldwide, creating new challenges in earthquake engineering and design. Many of the current analysis methods cannot be extrapolated beyond the definition under which they were established. Prior studies and existing seismic design guidelines have indicated that the current fixed-base hypothesis...

Article
This work presents a critical state plasticity model for predicting the response of sands to cyclic loading. The well-known bounding surface SANISAND framework by Dafalias and Manzari is enhanced with a memory surface to capture micromechanical, fabric-related processes directly affecting cyclic sand behavior. The resulting model, SANISAND-MS, was...
Article
Full-text available
The gas-liquid mass transfer coefficient is a key parameter to the design and operation of biotrickling filters that governs the transport rate of contaminants and oxygen from the gas phase to the liquid phase where pollutant biodegradation occurs. Mass transfer coefficients are typically estimated via experimental procedures to produce empirical c...

Blades are one of the main and more costly components of wind turbines and, besides, are difficult to inspect and maintain. Due to operational conditions, wind turbine blades (WTBs) are prone to suffer structural damage, chiefly because of fatigue or extreme loading. Therefore, it is crucial to monitor the state of health (SoH) of these components...

Earthquake-induced build-up of pore water pressure may be responsible for reduced soil capacity, while accumulation of shear strains may lead to violation of serviceability limits. Predicting accurately the soil cyclic behaviour in relation to seismic numerical simulations is still a challenging topic in many respects. Efforts are required to impro...
Conference Paper
Full-text available
It has been widely recognized that soil-structure interaction (SSI) can have a significant effect on structural performance during seismic response. This effect varies depending on structural and local site characteristics, meaning that general conclusions, relevant to a large class of structural and site characteristics, cannot be drawn. In this s...

Full-text available
In soil-structure interaction modeling of systems subjected to earthquake motions, it is classically assumed that the incoming wave field, produced by an earthquake, is unidimensional and vertically propagating. This work explores the validity of this assumption by performing earthquake soil-structure interaction modeling, including explicit modeli...
Conference Paper
Full-text available
To this date, earthquake-soil-structure interaction (ESSI) studies have used detailed models of near surface geology (Yang et al., 2003; Jeremić et al., 2012), with input motions such as planar incident waves or scaled recorded ground motions. There has been no direct inclusion of physics-based finite fault synthetic ground motion in ESSI study cas...

Nuclear facilities are a unique element of infrastructure that can impact many facets of a community’s resiliency. They not only serve as commercial power generating plants, but also as nuclear materials and nuclear science facilities for agencies such as the US Department of Energy (DOE). Nuclear facilities are typically characterized by a relativ...

Advances in high performance computing allow for large scale, high fidelity modeling of fault, path and soil structure interaction effects for Nuclear Power Plants (NPP). In this paper, we present a methodology to develop seismic motions that will propagate from the fault, through rock and eventually through soil to the NPP soil structure system. F...
Conference Paper

Described here is the use of time domain nonlinear analysis for design and assessment of nuclear power plants. The seismic input is defined as time-history defined by the site specific UHS. Non-linear contact (stick-slip and gaping) at the bottom of the structural model (between foundation slab and soil/rock beneath) represent the only nonlinear be...
Article
Conventional acceleration records do not properly account for the observed coseismic ground displacements, thus leading to an inaccurate definition of the seismic demand needed for the design of flexible (long period) structures. Large coseismic displacements observed during the 27 February 2010 Maule earthquake suggest that this effect should be i...
Article
Tall buildings and flexible structures require a better characterization of long period ground motion spectra than the one provided by current seismic building codes. Motivated by that, a methodology is proposed and tested to improve recorded and synthetic ground motions which are consistent with the observed co-seismic displacement field obtained...

In the context of 1-D seismic site response analysis, soil plasticity is related to elongation in fundamental period of sites. Counterintuitively, we have recently shown (upcoming paper) that dilatant soil deposits, such as those composed of dense sands, when modeled as a 1-D site can result in reduction of the fundamental period. It is the goal of this project to verify numerically if this feature of dense soils is persistent when full 3-D analysis is performed.
