In this paper  the ambient vibration measurement was conducted on a 86metershigh framewall tall building. This building  consists of two towers connected by air corridors and an enlarged base. Translational and torsional modes are  measured.  SATWE  module  in  PKPM  software  is  used  to  model  the  structure  and  the  analytical  modes  are  calculated.  It  is  found  that  due  to  the  eccentricity  of  the  air  corridors,  each  mode  shape  in  the  structure  has  component  of  torsional  vibration,  and  the  higher  modes  are  all  torsional  modes.  In  comparison  with  the  experiential formulas used in calculating fundamental period of tall building in different country, it is found that  the  measured  fundamental  period  of  the  structure  is  higher  than  the  results  by  calculation.  It  shows  that  the  measured  stiffness  of  the  structure  is  higher  than  that  of  the  analytical  model.  At  last  the  designed  ground  motions  are  used  in  the  elastic  dynamic  time  history  analysis  by  using  Newmarkb  method,  and  the  results  show  that  the  response  forces  concentrate  on  the  transfer  story  and  the  highest  air  corridor  on  the  top  of  the  tower,  and  the  shear  forces  have  greatly  changed.  Due  to  the  connection  of  the  air  corridor,  the  bending  moments and lateral displacements are approximately equal to each other in X and Y direction.
