Abstract:
Carbon Fiber Reinforced Polymer (CFRP) products have been used tostrengthen a variety of structures. They offer very high tensile strength and offerunique advantages in projects where access is limited. This paper presents the retrofitof a high-rise building in San Juan, Puerto Rico which was necessitated as a result ofchange in use. Unidirectional carbon fabrics and plates were used to strengthen thefloor beams and slabs in flexure. The location of the floor (on the 12th story) and thefact that the partition wall frames were already installed provided unique challenges tothis project and limited the strengthening alternatives. The project was completed intime and within budget. Field tests on the installed materials demonstrated that theFRP system met or exceeded the strength values claimed by the materials supplier.
