Application Development of Tensile Value with Prestressing Cramp Iron
Fan Xiang Zeng · Applied Mechanics and Materials · 2012
Abstract: Tensioning for Concrete cramp iron usually is controlled by two rule: controlling tensioning stress is main, measuring elongation is auxiliary. The rate of elongation value is only for checking data. In this article, the author describes that if applying mathematics theory in forecasting the tensile value of prestressing cramp iron, the estimation for the tensile value will be more accurate. By more accurate value, the elongation measuring method can become a un-auxiliary method for tensile controlling method.
