000223604 520__ $$aPunching  shear  is  usually  the  governing  failure criterion  for  the  select ion  of  the  depth  of reinforced concrete footings. Despite the fact that large experimental programmes have been performed  in  the  past  aimed  at  the  punching  strength  of  slender  flat  slabs,  only  a  few experimental  campaigns  on  full-scale  compact  reinforced  concrete  footings  can  be  found  in the literature. In this paper, the results of an experimental programme including 8 reinforced concrete  footings  with  a  nominal  thickness  of  550  mm  is  presented.  These  experiments investigated  the  influence  of  the  column  size,  member  slenderness  and  the  presence  of compression  and  shear  reinforcement.  The  test s  were  performed  using  an  innovative  test  setup  to  ensure  a  uniform  soil  pressure.  The  experimental  results  show   that  the  slenderness influences the punching shear strength as well as  the effectiveness of the shear reinforcement.   It  is  also  experimentally  shown  that  an important  interaction  amongst  bending  and  shear   occurs  for  high  levels  of  shear  forces  near  the  column  (typical  case  of  compact  footings  or members  with  large  amounts  of  shear  reinforcement).  Different  continuous measurements recorded  during  the  experimental  tests  allow  a  complete  description  of the kinematics  and   strains  at  failure.  On  that  basis,  experimental  evidence  is  obtained  showing  that  crushing  of the  concrete  struts  near  the  column  is  the phenomenon  that  triggers  the  punching  failure  of compact footings.
