EXOSKELETON  Steel  is  chosen  for  this
 EXOSKELETON


         steel other than timber or
         reinforced concrete is due
         to steel’s tensile strength
         primarily.    The     main
         purpose  of  inclusion  of
         steel is resist tensile
         stress     in    particular
         regions of the building that
         may cause structural
         failure or cracking. Load
         transfer          primarily
         happens through this
         system causing internal
         cores  to  bear  minimal
         gravity loads, floor slabs
         do  not have  to transfer

         loads and floor plates do
         not have to be same shape
         each floor. This diagrid
         framing system allows
         internal space to be bigger                                             The diagrid system design is
         due to lesser internal                                                  based on the strength required
         columns required.                                                       in  different parts  of  the

                                                                                 the strength of the areas in the
