【提要】 通過預(yù)應(yīng)力索拱體系在包頭一機(jī)展覽館中的應(yīng)用，對索中預(yù)應(yīng)力值的確定、索張拉方式的選擇以及索節(jié)點的處理作了一定的探討；同時比較了預(yù)應(yīng)力索拱體系和拱柱體系的特點。分析結(jié)果表明，索拱體系的采用使得工程的用鋼量大大減少。由于工程設(shè)計與施工緊密結(jié)合，使設(shè)計合理，施工也大大簡化。

Application of Prestressed Cable and Arch System at Baotou Yiji Exhibition/Zhu Yifeng,Li Ce
(Central Research Institute of Building and Construction of MCC Group，Beijing 100088 China)
Abstract:Through the application of prestressed cable and arch system at Baotou Yiji exhibition,some explorations have been made on deciding the value of prestress in the cable,selecting method of drawing cable and dealing with the junction of cable.The characteristics of the prestressed cable and arch system and the archcolumn system have been compared. The analysis results show that the steel usage of the engineering reduces largely because of the application of the cable and arch combination structure system.
