ST-10-06  aThe main objective of the study is to carry out an experimental program for  strengthening of the beams by using high performance laminate. The flexural behavior of  six  beams  strengthened  on  the  soffits  by  using  ferrocement  laminate  made  of  modified   mortar and reinforced with hexagonal wire mesh were compared with the controlled beam.  The  main  parameters  used  in  this  study  were  the  optimization  of  mortar  matrix  and  the   number of layers of wire mesh used in the fe rrocement form. The results of this experiment  include  first  crack  load,  ultimate  load,  defl ection  characteristics,  toughness  index  and   failure  pattern  after  the  strengthening  of  the  beams.  Also,  the  scope  was  to  determine  the   effect  of  the  modified  mortar  matrix  and  the   layers  of  wire  mesh  on  the  load  capacity  of   RC beam.            The  test  results  showed  that  strengthening  of  the  beams  by  using  high  performance   ferrocement jacketing increased on the load carrying capacity of the composite. The more  the number of layers of wire mesh, the higher  the increase in load carrying capacity of the  beams.  Moreover,  the  using  of  high  performance  mortar  indicates  the  highest  first  crack   load among all the strengthened specimens because its compressive and flexural strength is  higher than other mortar matrix.   aA thesis submitted in partial fulfillment of the requirements for the degree of Master of Engineering in Structural Engineering, School of Engineering and Technology  aThesis (M.Eng.) - Asian Institute of Technology, 2010 0aConcrete beams 0aStrength of materials0 aSun Sayamipuk,eExamination committee1 aAnwer, Naveed,eExamination committee0 aPennung Warnitchai,eChairperson2 aStrengthening of Higher Education Program(SHEP), Afghanistan,eScholarship donor2 aAsian Institute of Technology.tThesis ;vno.
