Abstract:Architectural design of 265.ft high building imposed severe structural restrictions which were met by using a lightweight structural concrete frame, concrete strengths as high as 6000 psi, and alloy steel bars with yield point of 82,365 psi in columns of lower stories. The saving in dead load combined with unusually high strengths of concrete and steel permitted the architect’s clearances to be maintained. Unusual structural design features are described as well as precast concrete grills which break up the direct rays of the sun against considerable areas of windows and walls.
