Behaviour of lightweight foamed concrete with pre-tensioning steel straps confinement

Due to its low compressive strength and ductility, lightweight foamed concrete (LFC) cannot be used in structural members such as beams, slabs and columns. One way to improve the strength and ductility of LFC is by confining the concrete laterally by using active external confinement. This research...
