Project Description: Due to some building modifications, the loading on several beams were being increased. There were new partitions and new concrete being added to the underside of the beams.
Solution: Fiber wrap was applied around column to increase the negative moment capacity, as well as, an application to the underside beam mid-span to increase the positive moment capacity. Tyfo® anchors were used to improve the development length in some areas. Fire-proofing was applied to the fiber wrap on the beam underside.
Summary: The fiber wrap offered an unobtrusive solution to handle the additional demand on the structure. The engineer (TGRWA) proposed two solutions - carbon composites or additional concrete. The composites proved to be more economical and competitive.
