Structural Building Design for Fifth Third Bank

This historical seven-story structure was built in 1927. The owner desired to expand building vertically to sixteen stories and horizontally one extra bay. Structural configuration presented a challenge where the building was un-symmetric. Unable to rig caissons underneath structure and type of steel grade were other challenges to be overcome.

A sixteen stories high building, approximately 150, 000 sq.ft. was constructed. Design of structure included; concrete slab composite deck, structural framing and bracing, rigid frames, spread foundations, and foundations on group of piles. Evaluation of original existing structure was simulated through three-dimensional analysis.
