Performance of post-tensioned wide band beam - column connections under seismic loading repaired using CFRP

The use of wide, post-tensioned band beams for floor systems is extremely common in Australia. They are required to be capable of deforming with a building during an earthquake, and are increasingly being used as part of the lateral resistance of a building. However, relatively little is known about their performance under earthquake loading. This paper presents the results achieved for a post-tensioned wide band beam subject to lateral loads, designed and detailed to resist gravity loading, and the reparation and re-testing using CFRP. The results achieved have shown that both this type of construction and this type of repair are capable of achieving sufficient drift ratios without significant loss in capacity for areas of low to moderate seismicity. There is also potential for use in areas of higher seismicity.
