FINITE ELEMENT ANALYSIS OF THE BEHAVIOUR OF REINFORCED CONCRETE COLUMNS CONFINED BY OVERLAPPING HOOPS SUBJECTED TO RAPID CONCENTRIC LOADING [PDF]
Civil Engineering Journal, 2017 The strain rate sensitivity of concrete material was discovered approximately one hundred years ago, and it has a marked effect on the behaviour of concrete members subjected to dynamic loadings such as strong earthquake and impact loading.

Characterizing the bond properties of automatically placed helical reinforcement in 3D printed concrete [PDF]
, 2022 The incompatibility of 3D concrete printing (3DCP) with conventional reinforcement methods is well known. Recently, solutions have suggested the insertion of helical reinforcement rods through a screwing motion into the freshly printed material.

Confinement of Prestressed Concrete Columns [PDF]
PCI Journal, 1988 P restressed concrete columns have several advantages over columns reinforced with deformed reinforcing bars as the main vertical reinforcement. Besides being economical to construct and transport, prestressed columns make use of both concrete and steel more efficiently and require a smaller amount of longitudinal reinforcement.
