［摘要］紹興體育會展館屋蓋結(jié)構(gòu)為梁端剛接張弦桁架，與梁端簡支的普通張弦梁在受力特點上有較為明顯的區(qū)別，故其拉索布置應(yīng)有所區(qū)別。研究表明，不同預(yù)應(yīng)力索端節(jié)點位置對張弦桁架內(nèi)力、整體穩(wěn)定都有較為明顯的影響，對豎向位移影響較小，幾乎不影響結(jié)構(gòu)整體動力性能。綜合分析后得出了最佳索端節(jié)點位置。深入對比三種典型橫向支撐系統(tǒng)布置方式的靜力、動力及屋蓋整體穩(wěn)定性能發(fā)現(xiàn)，間接連續(xù)布置的橫向聯(lián)系桁架對屋蓋結(jié)構(gòu)整體的綜合性能最為有利。

Abstract:Rigid connected truss string is adopted in the roof of Shaoxing Sports Exhibition Hall. Compared with hinged connected truss string, some distinguishing features of bearing capacity have been found. Therefore, the arrangement of pre-stressed cables is different. Several schemes had been researched, which have different position of pre-stressed cable’s stretching end. The results indicate that the position greatly influences on internal force and overall stability of these truss strings. Also, it has little influence on vertical displacement, and it does not change the dynamic performance of the structure. The best position of pre-stressed cable’s stretching end is proposed by analyzing of these results. The static behavior, dynamic performance and overall stability capacity of three transverse brace system with typical arrangement modes were studied. The results show that the comprehensive properties of the whole roof structure are the best while indirect continuous transverse truss has been arranged.
Keywords:rigid connected truss string; pre-stressed; stretching end node; transverse truss; overall stability
