Abstract: A composite elevated storage tank is constructed utilizing precast concrete panels for a pedestal which supports a steel storage tank. The precast concrete panels are poured in a controlled environment not subject to the difficulties inherent with sitecast concrete construction. A simple and practical method of attaching the panels to each other as well as to the foundation and steel tank ensures the concrete pedestal behaves as a shell to sustain all loads. This method, which uses cast in plates welded together at vertical joints and vertical aligned threaded rods for horizontal joints, serves to reduce the length of time required to construct a composite elevated tank and also reduces the construction costs.
