The Study Of Prestressed Steel Structure Anchor System And Forming Technology

As a novel structural style,Cable-prestressed Steel Structure(CSS) have widely applied inchina,and prossess capacious prospec.Although the relative research has been carried Out andobtained some achievenents,the study of anchor system,which are the key elements of CSS andhave important value in guiding execution practice,stay in the starting point, and can' form athorough theouy system.This situation will obstruct further application of CSS.The work of thispaper tries its way to develop the research on the subject.-- bostics, nd clasds manner in reSpo Of opssed pel to in thepe Thred comPuhag the PtDbam in the ~ed ed structhal, it i8 wt and instantto StUdy --the the anot SySteIn anu fonning tectriloarW with the for of wtssed ler Sywt eaCh comPOSbo of anot SyStem is~ on the rnatw of hation and forstics. mp the StUdy of anchor Syta fOurpe ofanchN dri are ed in pe nd be, are ed.
