Haines, Gipson, & Associates, Inc. provided consulting engineering services for the renovation of the 9-story AT&T office building in Memphis, TN. This structure, originally built in the 1960’s, is composed of a concrete encased steel frame, in-filled with concrete masonry walls.
Cracks developing in the brick veneer and concrete supports created concern and upon initial inspection, it was determined that there were no brick ties in place throughout the entire building. Brick veneer was observed to be leaning away from the building due to the lack of lateral ties. In addition, no intermediate supports were provided at story floor levels, therefore one concrete ledge at the second floor level was the sole support for the eight stories of brick above. This concrete ledge showed severe signs of shear failure. In addition, concrete spalling and deterioration was observed throughout the structure.
HGA provided solutions to remove and replace the exterior brick veneer. Brick ties were utilized to provide lateral attachment for the brick to the existing building structure. In addition, vertical supports were added to each story level. HGA also provided the design and detailing of new parapets to replace the pre-existing poorly constructed parapets.
