the seismic assessment of an existing structure is a complex procedure. In the evaluation of the structural capacity, difficulties arise in the definition of the lateral resisting members, in the estimation of the lateral capacity from component to system level. the identification of the local and global mechanisms, depending on the hierarchy of strength at subassembly level, is a challenging task. Nowadays, advanced numerical analysis procedures, implemented in user-friendly commercial software, are commonly adopted in the current practice to overcome the difficulties in the use of non-linear analyses. Nevertheless, their accuracy strongly depends on the ability of the numerical model to capture all the probable failure mechanisms. To help the user in the assessment of the probable failure mechanism and to have a first estimation of the building lateral capacity, the Simple Lateral Mechanism Analysis (SLaMA) method has been recently developed and included in the NZSEE 2016 guidelines. SLaMA is a simple and reliable "by-hand" tool to derive the local and global mechanism of a structural system and the corresponding capacity curve. this paper deals with the application of the SLaMA to an existing RC building severely damaged during the Christchurch earthquake (2011, New Zealand). the lateral capacity of four 2D resisting systems was assessed following the SLaMA method. the results of a refined nonlinear numerical model were used to assess the accuracy and reliability of SLaMA. the good match confirmed that SLaMA can be a useful and simple tool to have a first estimation of the building lateral response. It allows to identify the main structural weaknesses driving the user to the development of more refined nonlinear models. © 2017 National Technical University of Athens. All rights reserved.

In the paper we deal with analytical and numerical methods for modelling phononic elastic structures subject to harmonic loading. the band gap prediction is based on the analysis of eigenvalues of the effective mass coefficients for a given frequency. Using a spectral decomposition method, the propagating and the evanescent modes can be distinguished in the frequency domain. We also developed a numerical scheme to simulate the wave response of the phononic 3D structures and plates, or beams in the time domain. Using the backward Laplace transformation, we obtain a model involving the intertia effects in terms of time convolutions, where the homogenized mass tensor serves as the convolution kernel. the aim of the reported modelling is to understand behaviour of the phononic structures subject to incident waves of frequencies falling in the partial (so-called weak) band gap intervals in which waves of certain polarizations cannot propagate. We discuss the issues related to the time-space discretization. numerical examples of how homogenized phononic structures respond to a harmonic loading are presented.

this article assesses the occurrence of resonance with the effects of geometric stiffness and creep in the vibration of a prestressed reinforced concrete beam. A mathematical model based on the Rayleigh method is used, designed to represent a simply supported beam, intended to function as the base of an engine. the gross cross-section of the beam is set to an arrangement of passive reinforcement that is able to resist the effort provided in the simulation, treated by the method of homogenized section. Creep is taken into account through a three-parameter rheological model that conduces to a temporal modulus of elasticity;a normal force of compression reproduces the post tensioning force, which changes the stiffness, and consequently, the natural frequency of vibration of the structure with time. the results from the numerical simulation indicate resonant and non-resonant schemes between the natural frequency of the beam and the frequency of the engine predicted in the mathematical considerations. © 2017 National Technical University of Athens.

the impact of liquefaction in building performance during earthquakes is an aspect that has been recently receiving more attention by the technical and scientific communities, in an attempt to reduce the vulnerability of structures located in loose sandy saturated deposits. Currently, the design of buildings in liquefiable layers is performed based on empirical rules, where the liquefaction potential and the ground settlements are usually assessed free-field conditions, i.e., neglecting the presence of the surface structures. Even in the probabilistic approaches that tend to incorporate Earthquake Liquefaction Induced Damages (ELID) from some case-histories that include buildings at the surface, have never incorporated foundations characteristics and loading conditions. However, recent advances in numerical modelling allow performing a more rigorous assessment of the effects induced by liquefaction, namely the settlements that are expected to occur in the spread footings of structures, one of the most common foundation system implemented in small-to-mid-rise constructions in Europe. therefore, the present paper focuses research on the assessment of the settlements due to earthquake-induced liquefaction that is being conducted within the european Project LIQUEFACT.

Soil Structure Interaction (SSI) is a complex phenomenon that may radically change the earthquake response of structural systems, as consequence of the variation of the natural frequency and the damping ratio. One of the most effective means for evaluating SSI is the use of physical models. In this study the physical model considered is formed by an oscillator founded on a group of piles embedded in a horizontally layered deposit of dry sand. the benchmark experimental campaign was carried out at the Bristol Laboratory for Advanced Dynamics engineering (BLADE) at the University of Bristol (UK), financed by the Seismic engineering Research Infrastructures for european Synergies (SERIES). An accurate parametric numerical study is performed and the results are discussed. the study investigates the effects of the dynamic properties of the oscillator on the period elongation and piles response. By means of advanced numerical analyses the outcomes of the present work provide insights into the quantitative evaluation of period elongation and the strength of inertial contribute to the bending moment at the pile head, when the system approaches resonance conditions. © 2017 National Technical University of Athens.

the assessment of the out-of-plane response of masonry has been largely investigated in literature assuming walls responding as rigid blocks or assemblies of rigid bodies. Several studies developed numerical integration of single-degree-of-freedom and multi-degree of freedom systems for the simulation of the OOP dynamic rocking response of simple mechanisms. Modelling the energy dissipation involved in such mechanisms is extremely important to capture the dependence of the damping phenomenon with the system frequency. Some studies, recurring to the classical hypothesis of the impulsive dynamics, simulated the energy dissipation by means of the coefficient of restitution assuming as the overall reduction of energy were concentrated at the instant of the impact. In other works, the damping force has been modelled as a velocity dependent acting force through a constant, variable or stiffness proportional damping ratio. the two damping models are compared highlighting advantages and shortcomings of each system. this paper proposes a numerical formulation for the direct equivalence of the two damping approaches for simple OOP one-way bending mechanisms assuming as force-displacement relationship nonlinear elastic tri-linear curves. © 2017 ECCOMAS Proceedia.

Modern cities require efficient mass transportation systems like subway and railway networks. Due to the lack of available space and also due to environmental concerns, it is usually preferable to use the underground space to construct such kind of infrastructures. In this context, several railway lines run in trench cross-sections in urbanized regions. this option permits to save space, allowing reducing the distance between railway lines and existing buildings. Due to that reduced distance, nearby buildings are exposed to relevant levels of vibrations that can annoys their inhabitants. In the present paper a numerical investigation about the dynamic aspects related with wave propagation due to railway traffic in trench cross-sections is presented. For that purpose, a 2.5D FEM-PML formulation is adopted for the simulation of the main system (track-retaining structure-ground), while the rolling stock is simulated by a multi-body approach. A reference scenario is previously presented, being followed by a parametric study where the influence of the geotechnical properties of the ground was analyzed.

A two-dimensional grain boundary formulation is presented for the micromechanical analysis of multilayer barium titanate ceramics. the boundary element formulation of the elastic problem is generated for the single grains of the polycrystalline as well as heterogeneous aggregation and the assumption of tractions equilibrium and displacements compatibility are considered in this paper for expression of the intergranular variable which play an important role in elastic analysis of polycrystalline and heterogeneous micro-structures. However, these assumptions are valid only in undamaged areas. To model intergranular damage initiations and evaluations, a mixed mode effective traction as well as cohesive law is considered. the single crystals of homogenous BaTiO3 are represented as anisotropic elastic regions and they are considered to be in contact with each other. So, the integrity of the collection must be guaranteed by applying equations on the interface of contiguous grains in different regions. the numerical modelling of the 2D polycrystaline has been done by developed technique and obtained results feats well with available data which confirm the reliability of the technique. Some numerical studies are provided to highlight the influence of piezoelectricity, metallic layers and predefined damages on the results. © 2017 International Center for numerical methods in engineering.

this paper provides the results of FEM simulation of dynamic tests recently performed in thessaloniki on a large-scale single-degree-of-freedom structure resting on a soft soil. the structure (named EuroProteas) was specifically designed to mobilize strong soil-structure interaction (SSI), being a particularly stiff structure founded on soft soil. It consists of a simple steel frame with removable X-bracings founded on a RC slab and supporting the superstructure mass of two RC slabs identical to the foundation slab. It is a totally symmetric structure. Subsoil stratigraphy and dynamic properties of the foundation soil are derived from extended geotechnical and geophysical surveys, including static and dynamic in-situ and laboratory tests. Extensive free- and forced-vibration tests were performed. this paper deals with one set of forced-vibration tests. An eccentric mass shaker was used as a source of harmonic excitation (finput = 3, 4.5, 5, 7 Hz and eccentricity 6.93kg-m) imposed on the roof of the structure. the structural response is recorded by seven accelerometers, five of which are located at the top of the roof slab and two at the top of the foundation slab. Soil response is recorded with seismometers installed on the free soil surface in both horizontal directions. Dynamic FEM modelling of the tests were conducted in the time and frequency domains in order to detect the main aspects of SSI, taking into account soil nonlinearity. numerical and experimental results were extensively compared. Very interesting results were reached above all in terms of the effects of soil-foundation interface behaviour.

In this paper the occurrence of flutter in a simplified blade cascade is analysed. the simplified blade cascade is formed by three flat plates, which perform a kinematic harmonic motion, each with a different inter-blade phase angle. the inter-blade phase angles are chosen in order for travelling wave mode of vibration to be present. the aim of the simulations is to determine the aerodynamic damping coefficients caused by the aerodynamic forces acting on the flat plates, which show whether flutter occurs. the non-linear system of Favre-averaged Navier- Stokes equations in ALE formulation completed by the Spalart-Allmaras turbulence model was chosen as the mathematical model. the simulations were performed using the developed inhouse CFD software based on the discontinuous Galerkin method, which offers high order of accuracy. © 2017 ECCOMAS Proceedia.
