Experimental and Theoretical Analysis of Hollow Steel Columns Strengthening by CFRP
Abstract: The need for
strengthening and retrofitting is well known and extensive research is
progressing in this field. The reasons for strengthening and retrofitting are
numerous: increased loads, changes in use, deterioration, and so on. In recent
years, the use of carbon fiber reinforced polymer (CFRP) for strengthening has
shown to be a competitive method, both regarding structural performance, and
economical aspects. Extensive research has been carried out in this field.
However, most of the research has been undertaken on concrete structures and
for confinement, flexural, and shear strengthening. Limited research has been
carried out on steel structures strengthened with CFRP. This paper presents
axially loaded steel columns strengthened for increased load. The topic is
studied theoretically and through laboratory tests. The theory covers
analytical methods. Carbon fiber reinforced polymers has been used to
strengthen the columns. The tests have been undertaken on full scale specimens,
non-strengthened for reference, partially strengthened and fully strengthened
