SUMMARY:Seismic performance of existing RC buildings: field evidences\, research and design standards
DESCRIPTION:Giovedì 5 Maggio si svolgerà presso l’aula Pedeferri (edificio 6)\, un seminario dal titolo “Seismic performance of existing RC buildings: field evidences\, research and design standards” tenuto dal prof. Humberto Varum\, professore presso il Dipartimento di Ingegneria Civile della Facoltà di Ingegneria dell’Università di Porto (FEUP). \nAbstract: \nThe existing building stock is characterized by multiple types of structural systems. Architecture requirements in many situations demanded complex structural systems\, sometimes not in line with the general structural design code recommendations. The structural solutions adopted in design may enforce stiffness and strength irregularities\, both in-plan and in-elevation. In other perspective\, many existing buildings with RC framed or walls structural systems may present strong irregularities\, particularly in the bottom storey\, due to the absence of infill panels\, for the location of stores or garages. \nIn this seminar\, it is given an overview of the damages observed in existing RC buildings in recent earthquakes. The strategy proposed in modern codes for the seismic design of buildings is briefly presented and discussed. A brief presentation of the research work (experimental and numerical) carried out at the University of Porto (FEUP) is presented. To conclude\, some suggestions of research lines are advanced in support to the future development of seismic design codes. \nSpeaker’s Biosketch: \nHumberto Varum is currently full professor at the Civil Engineering Department of the Faculty of Engineering of the University of Porto (FEUP)\, Portugal. Previously\, he was associate professor at the Civil Engineering Department of the University of Aveiro\, Portugal\, where he had taught from 1997 to 2014. Since October 2010\, he is Honorary Lecturer at the Department of Civil\, Environmental and Geomatic Engineering\, University College of London (UCL)\, London\, United Kingdom. In 2012\, he was professor of the Master in “Evaluation Control and Reduction of Environmental Seismic Risk”\, at the University of Rome “La Sapienza”\, Rome\, Italy. Since July 2016\, he is Visiting Professor at the College of Civil Engineering\, Fuzhou University\, Fujian\, China. He is director of the PhD program in Civil Engineering at FEUP.

SUMMARY:PhDTalks | A local model of snow–firn dynamics and application to the Colle Gnifetti site
DESCRIPTION:Il nostro prossimo appuntamento con il Seminario PhDTalks si svolgerà lunedì 9 maggio 2022 nell’aula 5.1.1 dalle 18:15 alle 19:15 CET. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLa speaker Fabiola Banfi condurrà un seminario dal titolo “A local model of snow–firn dynamics and application to the Colle Gnifetti site”. \n \nAbstract: \nClimate changes require to move the boundary of firn models from snow accumulation to meteorological forcings. In this context\, we integrated the equations of snow and firn evolution into a local model. This was applied to the Colle Gnifetti site\, whose peculiarity is the intense snow erosion driven by wind. In this PhD Talk\, the model and application are presented\, with a focus on the challenges faced and still to be faced. \nL’evento sarà in presenza presso l’aula 5.1.1\, Politecnico di Milano\, Piazza Leonardo da Vinci\, 42\, 20133 Milano.\nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSe sei interessato a presentare durante uno di questi eventi\, invia una e-mail a andrea.opreni@polimi.it se fai parte del programma ISSG oppure a chiara.recalcati@polimi.it se stai frequentando il programma IAI.

SUMMARY:Twist and Shout: Elastic Orbital Angular Momentum
DESCRIPTION:Venerdì 13 Maggio si svolgerà presso l’aula De Donato (edificio 3)\, un seminario dal titolo “Twist and Shout: Elastic Orbital Angular Momentum” tenuto dal Dr. Gregory James Chaplain\, ricercatore del Dipartimento di Fisica e Astronomia presso l’Univeristà di Exter (UK). \nAbstract: \nWe identify that guided flexural waves in pipes carry a well-defined orbital angular momentum (OAM)\, associated with the compressional dilatational potential. The transfer of elastic OAM can be achieved through the coupling of the dilatational component of ultrasonic waves in the pipe with the pressure field in a fluid in which the pipe is partially submerged; the circumferential distribution of the stress in the pipe act as a continuous phased pressure source in the fluid\, resulting in the generation of Bessel-like acoustic beams. We demonstrate the existence of elastic OAM through theory and observe its transfer via simulation that is corroborated experimentally. \nSpeaker’s Biosketch: \nGregory is from Dundee\, Scotland\, where he lived until moving to Glasgow in 2012 to undertake an MSci in physics at the University of Glasgow. Afterwards he moved to Imperial College London where he obtained a PhD in applied mathematics under Prof. Richard Craster\, winning the Yael Dowker Prize for best mathematics PhD thesis for his research into wave propagation effects in structured materials. He continuted at Imperial as a doctoral prize research fellow before being awarded a Research Fellowship from the Royal Commission for the Exhibiton of 1851 at the University of Exeter in 2021.\nHis research interests include manipulating wave propagation using structured materials and metamaterials\, across a variety of wave regimes from electromagnetism to elasticity\, with a focus on applications in energy harvesting and vibration control.

SUMMARY:PhDTalks | Development of a σ-only twofluid model for the prediction of pseudo-homogeneous slurry pipe flow
DESCRIPTION:Martedì 24 maggio nell’aula 5.1.1 dalle 18:15 alle 19:15 CET si svolgerà il nostro prossimo incontro PhDTalks. \nPhDTalks è una serie di seminari e discussioni tra dottorandi. Gli eventi hanno lo scopo di fornire un luogo dove creare un network tra dottorandi ed entrare in contatto con i molti progetti sviluppati nel nostro dipartimento. \nLo speaker Qi Yang condurrà un seminario dal titolo “Development of a σ-only twofluid model for the prediction of pseudo-homogeneous slurry pipe flow”. \n \nAbstract: \nSlurry pipe flows are involved in many engineering applications. Over recent decades\, many efforts have been dedicated to slurry pipe flows due to the complexity of the system. The well established ? − ? two-fluid model is capable to predict the critical variables\, such as mean phase velocity\, concentration profile\, hydraulic gradient. Further assessment of predictive capacity of the ? − ? model was performed and an effective calibration strategy was proposed and verified. An improved ? −only model was developed and distributed through OpenFOAM. \nL’evento sarà in presenza presso l’aula 5.1.1\, Politecnico di Milano\, Piazza Leonardo da Vinci\, 42\, 20133 Milano e live al seguente link.\nAl termine dell’evento sarà disponibile un piccolo rinfresco finanziato dal dipartimento. \nSe sei interessato a presentare durante uno di questi eventi\, invia una e-mail a andrea.opreni@polimi.it se fai parte del programma ISSG oppure a chiara.recalcati@polimi.it se stai frequentando il programma IAI.

SUMMARY:Performance-based Optimisation of Energy Dissipation Systems for Seismic Applications
DESCRIPTION:Lunedì 30 Maggio si svolgerà presso l’aula Fassò\, un seminario dal titolo “Performance-based Optimisation of Energy Dissipation Systems for Seismic Applications” tenuto dal Dr. Iman Hajirasouliha\, Professore associato in ingegneria strutturale e leader del gruppo di ingegneria sismica (EEG) presso l’Università di Sheffield\, UK. \nAbstract: \nEnergy dissipation devices are increasingly used for seismic strengthening of existing buildings or as efficient seismic resistant systems in modern construction. However\, optimum design of these devices in multi-storey buildings can be a challenging task due to their complex behaviour and high computational costs. This study presents a practical multi-criteria performance-based optimisation framework for more efficient design of non-linear dampers under seismic loads. The proposed method is based on the concept of Uniform Distribution of Damage and can significantly reduce (up to 300 times) the computational costs compared to conventional optimisation methods such as Genetic Algorithm. To improve the convergence rate\, an adaptive formulation is developed that is modified in proportion to the level of performance violation. The proposed method can be efficiently used to satisfy multiple performance objectives in line with performance-based design recommendations of current seismic codes. The efficiency of the framework is demonstrated for steel frames with non-linear viscous as well as RC frames equipped with a novel friction-based wall damper. It is found that the optimum damping distribution identified by the proposed methodology consistently leads to considerably lower local and global damage indices compared to the solutions with an equal-cost uniform damping distribution. \nSpeaker’s Biosketch: \nDr Iman Hajirasouliha is an Associate Professor in Structural Engineering and Leader of Earthquake Engineering Group (EEG) at the University of Sheffield\, UK. He has over 20 years of research and consultancy experience in the fields of earthquake engineering\, performance-based optimisation\, light-weight structures\, energy dissipation devices\, and novel strengthening techniques\, leading to over 150 refereed journal papers and 100 conference publications in these areas. He has been Principal or Co-investigator of over €9M EU and UK funded projects led by his group. Dr Hajirasouliha is a member of several national and international technical committees and research networks\, including fib Task Groups 6.6 and 7.6 and IABSE Task Group 1.1. He is currently Associate Editor of Practice Periodical on Structural Design & Construction (ASCE)\, International Journal of Earthquake and Impact Engineering (IJEIE) and Frontiers in Built Environment (Earthquake Engineering Section).
