Summary

My research activity spans across the length scales, from detailed material microstructure to in-situ conditions, from soils to structures;  at the same time, they have made important contributions in advanced soil mechanics laboratory testing and soil reinforcement.

My research interests have been pursued under three generic themes:

  • Advanced soil mechanics laboratory testing and equipment developments

I have acquired high expertise in using various soil mechanics apparatus by working in experimental research projects in Bristol, Grenoble, Lyon (MSc, PhD). I have developed innovative local axial strain measurement systems for triaxial, hollow cylinder torsional and cubical cell apparatus for pre-failure deformation (stiffness) and large strain characterisation of the behaviour of soils by continuous tests on single specimens. I have been invited to join the International Technical Committee of experts in Laboratory soil mechanics testing (TC101) in 2011 and and I am currently serving as Secretary, since Sept. 2013. The role of the TC101 is instrumental in promoting internationalco-operation between academics and practitioners, and exchange of information concerning research and developments in advanced laboratory geotechnical testing. TC101 activity is overseen by the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE).

  • Investigation of soil behaviour (testing and modelling) from micro to macro length scales

My interest in the micromechanical description of soils focuses on the following topics: seismic wave propagation through granular media under multiaxial stress conditions (joint Bristol/Imperial College London EPSRC research project, EP/G064180), time effects in sands (collaboration in progress with Dr. B. Cazacliu, IFSTTAR Nantes, France), and fibre reinforced soils (collaborations with Dr. K. Maeda, Nagoya Institute of Technology, Japan, University of Grenoble, Prof. Cino Viggiany, Dr Ando Edward).  The laboratory macro element testing concerned extensive studies on soil liquefaction under monotonic loading, mechanics of fibre reinforced soils and constitutive modelling developments. While determination of fibre orientation is recognised by peers as being new and innovative, the work on liquefaction prevention and fibre/matrix interaction mechanism opens new perspectives on the use of fibre technique for the reinforcement of soils.  This work includes an invited paper for a Special Issue on New Horizons in Earth Reinforcement, Geotextiles and Geomembranes Journal. Two new lines of research consider the behaviour of soils mixed with soft rubber inclusions and advanced investigations and characterisation of crushing of granular materials.

 

  • Structural dynamics of real buildings, including soil-structure interaction problems

This research area involves: the situ dynamic testing of existing buildings before and during demolition and seismic vulnerability assessment based on analytical developments (collaboration with the earthquake research team of ENTPE Lyon, France); phenomenological aspects of the dynamic interact ion problem between soil and long inclusions through a physical shaking table set-up (EU FP7 international collaboration under SERIES programme); dynamic interaction between adjacent buildings (collaboration with Dr Nick Alexander); dynamic pile-soil-interaction in liquefiable soils (joint Bristol/Oxford EPSRC research project, EP/H015345).

 

Biography

Dr Erdin Ibraim is Senior Lecturer of Civil Engineering since 2007 and was appointed as Lecturer in the Department of Civil Engineering at the University of Bristol in 2000, joining the Geomechanics Group.  Prior to the current appointment, Dr Ibraim held a two year Research Assistantship position at the Ecole Nationale des Travaux Publics de l'Etat (ENTPE) of Lyon, France  working on the Seismic vulnerability of existing buildings: small amplitude in situ measurements and analytical formulation of the seismic integrity threshold. In the same establishment, Dr Ibraim was awarded a PhD in 1998 (Différents aspects du comportement des sables à partir d’essais triaxiaux: des petites déformations à la liquéfaction statique) and MSc in 1993 (Comportement de sables à l’aide d’essai sur cylinder creux: observations expérimentales et conditions d’utilisation de capteurs sans contact).  He was the beneficiary of University of Bristol Research Fellowship (2005-2006).
 
Dr Erdin Ibraim is an Editorial Board member for Géotechnique Journal since December 2010 and a member of the Editorial Board and Coordinator for Europe of the International Society for Soil Mechanics and Geotechnical Engineering (ISSMGE) Bulletin since March 2009.  Since November 2009, he is also serving as member of the ISSMGE Student and Young Member Presidential Group (SYMPG).
 
Dr Erdin Ibraim is a core member of the ISSMGE Technical Committee TC101: Laboratory Stress Strength Testing of Geomaterials (since October 2010).  He is also a member of British Geotechnical Association (BGA) since 2008, Association Française de Génie Parasismique (AFPS) since 1998, and has been a member of Alliance of Laboratories in Europe for Research and Technology (ALERT Geomaterials).
