    Development of CFRP wrap system for HDB columns
    Project Description

    Fibre reinforced polymer (FRP) systems are used to wrap HDB columns. A project was carried out to develop a composite wrapping system for the HDB columns. Comprehensive aspects were studied to obtain optimum strengthening effects: various wrapping patterns, fibre angles, fibre weaving patterns, the number of layers, tensioning of fibre during application, fibre overlap length, scaled-down column testing with and without wrap, etc. We achieved 20~41% increase of axial load capacity by using various wrapping designs.
