3.This article comtined the practice of the projtct of Jiaojiang bridge and analyzed strandwire with high strength and low laxation, the anchorage system, the tentioned technice in the construction, and the principle of anchorage.
4."Litz" wires using outer wraps or cores other than just another strand of wire (e.g. dacron, fiberglass, aramid fiber, etc.) are not to be used unless specifically called out under "Magnet Wire" in the construction details.
9.To find the reasons that caused(1860MPa) PC steel wirestrand rupture,fractures of detection and rupture in construction were studied by using the method of statistical analysis and morphological analysis.
