Abstract: To introduce the performance parameter of strand, loss of prestress in the construction process of pretensioning prestressed stee l strand and measures of reduce losses, failure analysis of prestressed stee l strand and so to the large- scale basic construction in China, the domestic prestressed strands industry had been well developed and met the demands of the architectural industry. At present, in China, prestressed technique has been widely used. Prestressed structure has e in the field of construction in China, a major structural materials. Expected within the next will get bigger and bigger development. Prestressed steel strand is prestressed industry wide application in metal products,so we need to have certain knowledge of strand.
Keywords: strand loss of prestress failure analysis
