[摘要] 新飛銷售大樓結(jié)構(gòu)設(shè)計(jì)中有許多技術(shù)難點(diǎn)，本文通過(guò)幾個(gè)方面的研究分析，對(duì)這些技術(shù)難點(diǎn)作了必要的處理。在該工程的建筑結(jié)構(gòu)中還有超出了常規(guī)的做法，為此采用了一些新的技術(shù)措施，從而使得結(jié)構(gòu)體系即滿足了建筑造型和使用功能上的要求，也確保了結(jié)構(gòu)的安全可靠。工程中采用了大跨度次梁預(yù)應(yīng)力樓蓋結(jié)構(gòu)，有效地降低梁的截面高度，確保層高和建筑物總高度的要求，此外還采用了超長(zhǎng)混凝土結(jié)構(gòu)無(wú)縫設(shè)計(jì)等新技術(shù)。該工程的綜合技術(shù)性能指標(biāo)非常好。

Abstract: There has many technical difficulties in the structural design of the Xinfei sales building, we have made necessary treatment to this technical difficulties in this paper through several aspects of research and analysis. There also has some aspects beyond the conventional practice in this project, so we take some new technical measures, which causes the structure system namely to satisfy in the construction modelling and the use function request, also has guaranteed the structure's security and reliability. The project has used large-span secondary girder pre-stressed ceiling structure, which effectively reduces the beam cross-section height and ensures the total height and building height requirements. In addition, this project has also used of ultra-long seamless design of concrete structures and other new technologies. This project's comprehensive technical performance target is good.
Keywords: secondary girder pre-stressed; ultra-long structure; structural design; steel structure, seamless design
