［摘要］弦支穹頂結(jié)構(gòu)體系是在單層網(wǎng)殼和張拉整體的基礎(chǔ)上發(fā)展起來(lái)的一種新型空間結(jié)構(gòu)。詳細(xì)介紹了上部為肋環(huán)型單層網(wǎng)殼的弦支穹頂結(jié)構(gòu)體系在連云港體育館屋面中的具體應(yīng)用。包括屋蓋結(jié)構(gòu)體系的布置特點(diǎn)，荷載取值，初始預(yù)應(yīng)力的確定原則，結(jié)構(gòu)力學(xué)性態(tài)分析以及拉索與撐桿連接節(jié)點(diǎn)彈塑性分析。最后，對(duì)該結(jié)構(gòu)作了彈塑性極限承載力研究，并就結(jié)構(gòu)的安全度作了探討。

Abstract:The suspendome system is a new-style space structure developed on the basis of single-layer dome structures and tensegrity systems. The application of suspendome system,in which upper rigid structure is single-layer ribbed dome,is introduced in roof of Lianyungang gymnasium,including the characteristic of the roof structure system,loads calculation,the principle of pre-stress value,static performance analysis and elasto-plastic analysis of the connection joint of cable and strut. Finally,the researches of structural ultimate bearing capacity have been carried out effectively by using elasto-plastic finite element method,and the structural safety has been discussed.

Keywords:suspendome; single-layer ribbed dome; pre-stress; ultimate bearing; safety
