DESCRIPTION:A shear crack in an RC beam undergoes a load sharing stage whe
 re aggregate interlock is dominant only in a particular segment at an angl
 e near the mid-portion. However\, one of the challenges is that\, this est
 imation of the aggregate interlock contribution is highly dependent on the
  shape of the critical shear crack. Therefore\, a thorough study is requir
 ed to determine the crack shape firstly on the measured cracking patterns 
 and subsequently on predicting the expected cracking pattern. This talk il
 lustrates the sensitivity of aggregate interlock action on simplified and 
 higher order shear crack geometries to assess the best ways of idealising 
 the shear crack such that it could be adapted in analytical tools.\n
