Structural Proposal
A proposed alternative system will be
studied in depth consisting of a full composite beam/composite deck
design to resist gravity loads and special reinforced concrete shear
walls to resist lateral loads (replacing braced frames). The core of
the building will be slightly altered to reduce natural eccentricities
created by lateral loads and to eliminate the need for transfer girders
at the perimeter. Upstate New York is a region of low seismic
activity, for which The First Albany Building performs adequately.
However, if a visually identical building was constructed in
Charleston, South Carolina; significant changes would be needed.
Charleston is at more risk for significant seismic activity and prone
to hurricanes. A building site will be chosen there and a new
structural system will be designed for the higher lateral design loads. A light weight structural
floor system combined with a lateral system with a higher response
modification factor would be ideal to minimize base shears.
Breadth Topics
Along with designing a new structural system, two breadth studies
shall be done in the construction management and mechanical options.
The breadth in construction management will be an investigation of the
scheduling and cost impact of switching to a full composite action
beam with reinforced shear wall design. Changes in the geographic
location will also be considered (weather, seasonal changes, local
labor and material costs). The Mechanical breadth work study will in
Energy Conservation and Energy Cost Considerations. Time of day usage
(energy storage methods), energy recovery (heat recovery), and
alternate energy sources will be explored to see where savings can be
made. Other areas to check are for in-efficiencies of mechanical
equipment and building envelope parameters for a location in a warmer
climate.
