SUMMARY:The need and state-of-the-art tools for rapid advances in global v

DESCRIPTION:In the 21st century vibration serviceability replaced strength
  as a governing design criterion for slender and lightweight structures\, 
 such as long open plan lightweight building floors or tall buildings.\nIn 
 2015 IStructE conducted a survey of structural engineering practitioners a
 bout their experience with designing structures to have satisfactory vibra
 tion serviceability. This was the first and the only international survey 
 of this kind ever conducted. Over 100 responses were received from around 
 the world. Almost a quarter of respondents had experienced problems with h
 uman comfort in designs which were code compliant and over 40% stated that
  they had experienced limitations in design code guidance/requirements. Th
 ese and responses to the other 8 questions\, as well as free text comments
 \, are analysed and presented\, with some recommendations as to the way fo
 rward for the profession considering the outcomes of this survey. Key area
 s of concern identified by the survey are: (1) generally low level of comp
 etence of structural engineers when dealing with vibration serviceability\
 ; (2) poor code and design guideline provision to cope with a plethora of 
 vibration serviceability scenarios in modern slender and lightweight struc
 tures\; (3) aspects of client-engineer relationship preventing full engage
 ment of the client in specifying vibration serviceability requirements\; a
 nd (4) unreliable or unworkable vibration limits proposed in the standards
 .\nThis talk will therefore present examples of the acute need and new sta
 te-of-the-art tools for state-of-the-art-vibration serviceability research
  in the UK and internationally.\n
