Description
Summary:The use of the seven-wire strand in pretension structures so far has shown that such strands have a relatively long development length. An attempt to reduce the development length is reflected through the idea of a different strand geometry that has a more favorable shape. This new shape should have a greater inclination of the outer wires, increasing the resistance that occurs when moving through the concrete. The idea is primarily about the triangular distribution of wires in the cross-section of the strand. This paper reviews tests related to the use of innovative, triangular, and ten-wire strands. The tests exclusively relate to the strands formed by the use of steel wires.
