ST-10-10  aA thesis submitted in partial fulfillment of the re quirements for the degree of Master of Engineering in Structural Engineering,  School of Engineering and Technology  aThesis (M.Eng.) - Asian Institute of Technology, 2010  aIn these days, hybrid precast concrete moment resis ting fames and shear walls were  constructed  in  many  regions  such  as  USA,  Japan,  New   Zealand,  etc  because  precast  concrete   system   is   easy   to   construct.   Besides,   it   h as   significant   benefits   in   cost  effectiveness,   time   saving   and   high   quality   product ion.   In   earlier   days,   monolithic  emulation  precast  concrete  systems  were  designed  to   use  in  seismic  regions.  However,  these  precast  concrete  systems  are  vulnerable  to  ea rthquakes.  Thus,  the  precast  concrete  systems that can resist the earthquake have been de veloping by many researchers.  Hybrid  precast  concrete  beam-column  frames  can  be  i mplemented  as  the  major  lateral  force  resistance  for  low-rise  and  mid  rise  building  without  any  major  design  difficulties. But it is becoming more and more diff icult to design the hybrid precast beam- column  frames  to  satisfy  the  seismic  design  require ments  when  the  number  of  stories  increases. If hybrid precast concrete beam-column f rames only is used, the frame becomes  too  soft,  and  deformation  and  strength  demands  tend   to  increase  beyond  the  economic  design  level.  Adding  hybrid  wall  into  the  beam-colu mn  frames  can  solve  this  problem  effectively.  In  this  study,  hybrid  precast  concrete   dual  system  was  selected  and  tested  to  examine the seismic performances and behaviors of h ybrid precast connections.  This dual  system was composed of Wall-foundation, column-foun dation, beam-wall, exterior beam- column  and  interior  beam-column  connections  in  orde r  to  understand  the  behaviors  of  various  types  of  hybrid  connections  at  one  time.  Th e  hybrid  precast  concrete  dual  system  for  this  experiment  was  subjected  to  quasi-static  c yclic  loading,  initiated  at  0.10%  story  drift and stopped at 2.50% story drift.   According  to  the  experimental  results,  the  hybrid  p recast  dual  system  performed  satisfactorily in terms of self-centering, stiffnes s degradation, strength degradation, energy  dissipation,  residual  displacement  and  shear  slip.  The  test  assemblage  had  good  self- centering  capacity  with  almost  zero  residual  displa cement  at  the  end  of  the  test.  As  there  was  no  pinching  in  hysteretic  loop  throughout  the  t est,  good  energy  dissipation,  low  stiffness  and  strength  degradation  could  be  achieve d  as  expected.  Shear  slip  did  not  also  experience  in  any  joint.  Moreover,  minor  damage  was   found  at  the  interfaces  of  all  connections and only hairline cracks could be detec ted in all precast concrete members. 0aPrecast concrete 0aWalls0 aPennung Warnitchai,eChairperson1 aAnwar, Naveed,eExamination Committee1 aPark, Kyung Ho,eExamination Committee0 aSun Sayamipuk,eExamination committee2 aAIT Fellowship,eScholarship donor2 aAsian Institute of Technology.tThesis ;vno.
