  Date of Birth: ۲۲ January ۱۹۷۹

I received the B.Sc. and M.Sc. degrees in Civil Engineering in ۲۰۰۰ and ۲۰۰۳, respectively, and Ph.D. degree in Structural Engineering from Sahand University of Technology in ۲۰۱۱. Currently, I serve as an Associate Professor of Structural Engineering and supervisor of M.Sc. thesis at Urmia University of Technology. During my career I have authored and co-authored over thirty peer-reviewed research articles published in the leading engineering journals and prominent conferences. I have also successfully co-authored three peer-reviewed books about structural stability published by SUT press. I was a member of scientific committees of the ۴th national conference on Spatial Structures and the ۱۲th national congress on Civil Engineering . I am frequently invited to judge the work of others in my field by high-status journals and conferences. I am also frequently invited to give lectures in the field of Space Structures. In ۲۰۰۸, ۲۰۰۹ and ۲۰۱۱, I won the best student and best researcher awards of the Sahand University of Technology. In ۲۰۱۱, I was also awarded the Active Researcher prize of East Azarbaijan province.

  ---------------------------------------------------------------------
 TECHNICAL EXPERIENCES:
۱- Performing Experimental Studies on Space Structures in structural laboratory of SUT and Safira Company. These included:

  • Overcoming important problems of the construction process of tensegrity systems. To do as, special connection type was designed for cable elements and precise rigs and platform were developed to construct and assemble of the systems.
  • Self-stress implementation of tensegrity systems. Experimental study on two ۳ × ۳ × ۰.۷ m tensegrity grids was conducted to verify the accuracy and validity of the numerical method.

  ۲- Tests on the constituent elements which includes tensile test of the cable elements, tensile test of the tubes used in the struts and buckling test of the struts.

  ۳- Collapse tests on tensegrity systems:

  • Full progressive collapse test on an experimental model: The model was loaded up to a load level at which buckling of a strut led to successive buckling of struts causing overall collapse.
  •  Evaluating the effect of sudden loss of a cable element at a specified load level on the behavior of an experimental model;
  •  Partial progressive collapse test on an experimental model. The model was designed in such a way to exhibit partial progressive collapse due to member snap;
  • Evaluating the effects of imperfection amplitude, damping factors and residual stress of the buckled struts on the progressive collapse of tensegrity systems

   ۴- Cyclic tests on steel plate shear walls:

  • Seismic behavior of LYS and HYS steel plate shear walls connected to frame beams only;
  • Seismic study on shear walls with fully-connected and beam-only-connected web plates.

WRITTEN BOOKS:

۱. Stability Analysis of Space Structures , By: K. Abedi and B. Shekastehband, ۲۰۱۰ in Persian.

  This book serves both as a textbook for postgraduate courses on stability analysis of space structures and a reference volume for engineers and scientists. We included some original derivations as well as many new research results not yet published in periodicals. The contents of this book contains fundamental of stability theory, different class of the instability phenomenon in space structures, static collapse analysis considering the nodal snap-through, static collapse analysis considering the member buckling phenomenon, dynamic collapse analysis considering dynamic propagation of a local nodal snap-through and member snap.

۲. Fundamental of Structural Stability , By: K. Abedi and B. Shekastehband, ۲۰۱۵ in Persian.

  The material contained in this text is ideally suited for postgraduate students in Civil, Mechanics and Aerospace Engineering. The topics presented in the text pertain to various aspects of elastic buckling and inelastic instability. The emphasis of the book is on the fundamental concepts and on the methodology developed through the years to solve structural stability problems. The book contains a detailed treatment of the different class of the instability phenomenon, elastic and inelastic stability analysis of columns, beams, beam-columns, frames, arches, plates and shells.

۳. Advanced Topics on Structural Stability, By: K. Abedi and B. Shekastehband, ۲۰۲۰ in Persian

  This book is by no means a comprehensive treatment of structural stability. However, it contains both numerical and experimental methods that could be of interest for a variety of structural specialists. Expert researchers will find the most recent progresses in the stability of structures, including advanced problems in Finite Element-related Stability treatments, Progressive Collapse phenomenon, and Dynamic Instability issue. Professionals will find many practical concepts and numerical results, useful for the design of skeletal structures made of traditional and advanced materials. They will be able to understand complex stability tests conducted on different parts of structures.
