| description | Steel strapping tensioning technique (SSTT) confinement has been proven as a type of
external confinement to retrofit and upgrade concrete structures. Their remarkable
enhancement to concrete mechanical properties, practicing active lateral
confinement, low cost, easy to operate, time saving and no structure interruption during
application have brought this technique as of the most affordable technique for column
confinement, especially for high strength concrete (HSC) which naturally behaves
insufficient in ductility. Although a great number of previous studies have demonstrated
the performance of SSTT confinement, there are several anxieties related to the long term
behaviour of SSTT confined columns which have yet been implemented especially in real
hostile condition. Environmental effects, such as ultraviolet radiation exposure and saline
solution (sea water) may affect the confining material properties, and therefore
decrease the performance of the confined columns. In this study a total of twenty HSC
specimens with dimension of 100 mm and 200 mm in diameter and height respectively
were prepared, volumetric-identically pre-tensioned with steel strap and exposed to
three conditions: indoor, outdoor and saline water for three months. The exposed
specimens were monotonically tested and their performance was studied through the
stress-strain relationship, mode of failure and degree of corrosion. The results show that
none of the forenamed environmental conditions have exaggerating influence on the
performance of the SSTT confined concrete specimens even some material has been
severely corroded. It is then parallel compared with existing FRP confinement studies and
the result proves that SSTT confinement able to possess the highest strength performance
under similar environmental exposure. |
