The use of continuous rectangular spiral shear reinforcement as transverse reinforcement is experimentally investigated by testing 28 reinforced concrete beams in a static four-point bending setup.
It is important to note that in addition to shear links, the alternative of using continuous spiral shear reinforcement was also investigated but was found less effective in producing sections with a constant core area resulting in less accurate replication of the cross-sectional capacity.
A low-dose CT scan was obtained first for attenuation correction by using a continuous spiral technique (120 kVp, 45 mA, 0.5 s rotation time).
In the Discovery STE scanner, whole-body CT was performed using a continuous spiral technique with a 16-slice helical CT (140 kV, 30 170 mAs with an AutomA mode, section width of 3.75 mm) 60 minutes after the injection of FDG (5.5 MBq/kg).
In the Discovery LS scanner, whole-body CT was performed using a continuous spiral technique with an 8-slice helical CT (140 kV, 40 120 mAs adjusted to the patient's body weight, section width of 5 mm) 45 minutes after the injection of approximately 370 MBq FDG.
These have a nearly continuous spiral of bracts, sepals, and petals, then numerous stamens, a nectary disc, and separate carpels with expanded stigmas.
Technical virtuosity dominated his prints; for example, the modelling of a face with one continuous spiral.
The use of a "spiral" to describe the journey is widespread.
It was shaped like a truncated top and its floor was a continuous spiral around an overweening core of empty vertical space.
Discrete hoop reinforcement is preferable over continuous spiral reinforcement due to ease of construction in bridge applications.
