DESCRIPTION:This presentation will give a flavour of some of the ongoing S
 tructural Engineering research at Bristol\, with a focus on the underlying
  mechanics.  First\, a study aimed at developing a suitable experimental s
 etup for local fatigue assessment of glass fibre reinforced polymer (GFRP)
  cellular bridge decks under wheel (or rather tyre) loading is described. 
  The crux of this problem is the detailing of a loaded-tyre substitute whi
 ch\, on application to the deck\, replicates the contact pressure distribu
 tion between the actual compliant pneumatic tyre and the flexible GFRP dec
 k.  The second example entails use of carbon FRPs to strengthen statically
  indeterminate reinforced concrete (RC) frames in flexure\,  Here\, a key 
 issue is the limited ability of the FRP-strengthened structure to redistri
 bute moments in the approach to failure and the associated implications fo
 r designing FRP strengthening of indeterminate structures in practice.  Th
 is will naturally lead on to analysis of generic indeterminate spans compr
 ising two distinct section flexural stiffnesses\, under different load for
 ms.  Some unanticipated and physically meaningful results emerge.\n
