Abstract

As a result of a new six-story addition, Backus Hospital in Norwich, Connecticut, USA needed to increase the height of an existing tapered brick stack or replace it. Whether the stack was replaced or upgraded, the hospital would not permit any significant interruptions in use. A simple extension of the existing stack alone was not appropriate because the height increase would produce additional forces and moments that required extensive strengthening of ,the existing stack and foundation. A completely new stack proved impractical and costly when compared to upgrading the existing one. The final solution described in this paper has several unique aspects. Primary among these is the structural system used. The new structure is essentially independent of the existing one. The aesthetics of the structure as well as the fabrication and erection procedures also played critical roles in determining the solution to a structural problem that had many imposed constraints.
