It has been shown that the forward splitter plate reduces drag by 13% as compared to the plain cylinder configuration.
The phase averaged PIV measurements reveal that the vortices shed in the forward splitter plate cylinder case are weaker in strength as compared to the plain cylinder case.
In the present study, wind tunnel experiments were conducted on such a modified cylinder and the results were compared to the reference case of a plain cylinder.
At subcritical Reynolds number, the flow separation is delayed and the shedding frequency is increased in the forward splitter plate cylinder case as compared to the plain cylinder case.
Standard plain concrete cylinders and CFFT cylinders were immersed in pure water, salt and alkaline solutions, and exposed to 200 freeze thaw cycles, between −40 °C and +40 °C.
A comprehensive experimental program which involves 54 plain concrete cylinders was conducted in this study.
Experimental results show that the use of glass fibre composite wrap can increase the load carrying capacity of the plain concrete cylinders with and without notch formation.
An experimental programme was undertaken to study the compressive strength and stress strain behaviour of both unconfined and FRP-confined plain concrete cylinders after being heated to various elevated temperatures for up to four hours and cooled to room temperature.
Eighteen plain concrete cylinders were preloaded at three different stress levels (i.e., up to f′co, 0.9f′co and 0.8f′co on the descending branch of the axial compressive stress-strain curve of plain concrete, f′co was compressive strength of plain concrete and was 37.7 MPa here) to represent the moderate, moderately-severe, and severe damage levels, respectively.
Plain concrete cylinders, twenty-six with 152 mm diameter and 305 mm height, and four with 100 mm diameter and 200 mm height, with cylinder compressive concrete strength 19 MPa, were wrapped with carbon- and glass-FRP jackets and tested under monotonic axial compression.
Three plain concrete cylinders (100 mm × 200 mm) for each of binder type and curing age were cast, for evaluating the chloride penetrability.
