［摘要］蘇寧易購(gòu)總部VIP門(mén)廳是一個(gè)單層鋼結(jié)構(gòu)建筑，為了實(shí)現(xiàn)建筑設(shè)計(jì)的大柱網(wǎng)、高細(xì)柱，結(jié)構(gòu)設(shè)計(jì)采用一種新型的結(jié)構(gòu)體系——帶柔性支撐的鋼框排架結(jié)構(gòu)，通過(guò)對(duì)其整體力學(xué)性能的計(jì)算分析和比較研究，以及對(duì)關(guān)鍵節(jié)點(diǎn)連接做法的構(gòu)造研究，論證了這一新型結(jié)構(gòu)體系的可行性。為了達(dá)到建筑設(shè)計(jì)要求的雙曲屋面，結(jié)構(gòu)設(shè)計(jì)采用一種斜置壓型鋼板與正放鋼梁的擱置連接方法，解決了雙曲屋面中壓型鋼板組合樓板與承重鋼梁的連接問(wèn)題，實(shí)現(xiàn)了壓型鋼板組合樓板在雙曲屋面中的應(yīng)用。相關(guān)內(nèi)容可為類(lèi)似工程的結(jié)構(gòu)設(shè)計(jì)提供參考。

［關(guān)鍵詞］鋼框架； 柔性支撐； 雙曲屋面； 組合樓板

Abstract:Suning Yigou headquarters′ VIP lobby is a single-storey steel structure building, in order to realize the design of large column network and high-thin columns in architectural design, a new structural system, steel frame bent structure with flexible support, was adopted in structural design. The feasibility of this new structural system was demonstrated through the calculation and comparison of its overall mechanical properties and the structural study of the connection method of key joints. In order to meet the requirements of architectural design for hyperbolic roof, a method of shelving connection between oblique profiled steel plate and positive steel beam was adopted in structural design, which solves the connection problem between medium-pressure profiled steel plate composite floor and load-bearing steel beam in hyperbolic roof, and realizes the application of profiled steel plate composite floor in hyperbolic roof. Relevant contents can provide reference for the structural design of similar projects.

Keywords:steel frame; flexible support; hyperbolic roof; composite floor
