| Abstract: | Taking the project of Guiyang Longdonbao Airport air control building for example,this paper discusses how to check material quality of twisted steel line,steel line bunch and anchor fixture used in post tensioned non spiced twisted steel line pre stressed concrete frame beam,and how to take accurate control of parameters such as tension,extension,friction resistance deformation,ect.Engineering practice indicates that the specially built test equipment and tools are convenient and reliable and the improvement measures are simple and easy to operate. |
