[提要]  結(jié)合南京新世紀(jì)廣場工程對(duì)高強(qiáng)砼預(yù)應(yīng)力桁架轉(zhuǎn)換層結(jié)構(gòu)的性能進(jìn)行了試驗(yàn)研究，在試驗(yàn)分析的基礎(chǔ)上，提出了預(yù)應(yīng)力砼轉(zhuǎn)換桁架的設(shè)計(jì)建議，為桁架轉(zhuǎn)換層結(jié)構(gòu)的設(shè)計(jì)和推廣應(yīng)用提供了可靠的實(shí)驗(yàn)依據(jù)。
[關(guān)鍵詞]  預(yù)應(yīng)力砼 轉(zhuǎn)換層 桁架 試驗(yàn) 分析

Combined with Nanjing New Centry Square Engineering, experimental study on the behaviours of pre-
stressed high strength concrete truss transfer storey structure are carried out. Based on the test results and analysis, the design proposals of prestressed concrete transfer truss are presented, which can provide reli-able experimental verifications for design and wide applications of truss tramsfer storey structure.
