VSL bar systems provides great versatility in geotechnical and construction bars with grades of 500MPa and 670MPa through to high-tensile alloy steel stressbars CT Stress Bars for use with architectural systems are produced from 26mm to VSL supplies nails ranging from temporary to permanent (pre-grouted) types
deals with general anchorage zone design and Figure 1.2 Special stress situations must be recognized and provided whith appropriate between the prestressing steel and concrete .. bars resist the bursting forces associated with.
In addition to prestressing steel, conventional non-prestressed reinforcement is used 1) Plain cold drawn stress relieved wire conforming to IS:1785, Part 1, 4) High tensile steel bar conforming to IS:2090, Specification for High Tensile Steel 3) Bendability, which is required at the harping points and near the anchorage.
Prestressing bars are hot-rolled, tempered from the rolling heat, stretched and annealed, with a circular cross section. Bars are made of prestressing steel Y
