ABSTRACT = {In  order  to  studythe  web-crippling  behavior  of  aluminum  hollow  section subjected  toconcentrated  load,  sixteen aluminum  hollow tubes withdifferent  loading conditions,  bearing  lengthandweb  slenderness  ratioswere  tested.  This paperalso discusseda  method  to  improve the web  crippling  strength  of  the aluminum  hollow sections  byinfilling  the  mortar  as  composite  section,  and  four  aluminum  composite sections  were  tested.  The  literature  has  reported  lots  of  web  crippling  tests, butthere isfew reportson web crippling behavior of aluminum composite sections. Interior-Ground(IG) and End-Ground(EG)loading conditions were adopted, with the  specimens placed on  the  ground  to  simulate  the  load  of  floor  joists. Specimens  were  also  placed  on  a bearing plate with end (ETF) or interior (ITF) bearing load.The influenceof supporting conditions,loading positions, bearing length and web slenderness ratioson web crippling ultimate bearingcapacityand  ductility  of  aluminum  hollow  sections  wasstudied.  The enhancements  of  infilling  mortar  were  also  evaluated.  The  results  obtained  from  the experiments show thatinfilling  the  mortar  inaluminum  hollow  tubesis  aneffective methodfor  enhancingthe ultimate  capacityof  theweb,  especially  for  specimens under Interior-Ground(IG)  condition.Based  on  the  results  of parameterresearch, this  paper proposes a  series of design formulas for well predictingweb  crippling ultimate capacity of  aluminum  hollow  and  composite  tubes  under  four different loading  and  boundary conditions.},
