DESCRIPTION:Conventional\, codified\,  methods of assessing the capacity o
 f reinforced and pre-stressed concrete half-joints  can  prove  excessivel
 y  conservative  when  applied  to  existing  structures\,  which  were de
 signed to less onerous standards and have suffered significant in service 
 deterioration. \n\nThis seminar will discuss the use of a three pronged ap
 proach to the assessment of an existing half-joint \nusing lower and upper
  bound plastic analyses\, supported by non-linear finite element methods. 
 This combined approach\, with cross pollination of mechanisms between meth
 ods\, sought to converge the assessed capacities from the three techniques
 \, producing a result  which is reliable without being excessively conserv
 ative. The approach is discussed with reference to the A14 Huntingdon Rail
 way Viaduct.\n\n
