[摘要] 江蘇建筑職業(yè)技術(shù)學(xué)院圖書館混凝土結(jié)構(gòu)體系外露，特有的八面柱、井字梁與斜柱勾勒出清晰的混凝土框架結(jié)構(gòu)體系。為配合建筑效果，結(jié)構(gòu)平面局部外挑尺寸較大，外圍局部結(jié)構(gòu)采用傾斜角度不等的型鋼混凝土柱進(jìn)行轉(zhuǎn)換，采用ANSYS進(jìn)行節(jié)點(diǎn)分析，多種軟件復(fù)核保證設(shè)計(jì)安全。本工程屬超長(zhǎng)結(jié)構(gòu)且平面較復(fù)雜，采用ETABS進(jìn)行樓板溫度應(yīng)力分析，設(shè)計(jì)時(shí)采取了相應(yīng)的措施減小了溫度效應(yīng)對(duì)結(jié)構(gòu)的影響。采用BIM三維可視化技術(shù)進(jìn)行設(shè)計(jì)，預(yù)演了三維管線排布，并利用碰撞檢測(cè)精確搜索排查錯(cuò)誤，提前規(guī)避了大部分設(shè)計(jì)變更與修改，為施工階段節(jié)省投資。

Abstract: The library of Jiangsu Jianzhu Institute was designed as an exposed structure system. The unique octagonal column, crossing beams and inclined bracings outline a clear appearance of concrete frame structure system. Inclined steel reinforced concrete bracings of different angels were arranged to fulfill the architectural effects, ANSYS nodal analysis was used to ensure safety. Due to super-long structure and complicated structure plane, using ETABS for the slab temperature stress analysis, several measures were taken to reduce the impact of the temperature effect on the structure. BIM technology was adopted to realize 3D visual design and to preview the 3D pipeline arrangement. The collision errors were found to avoid the most design changes and modification in advance, saving the investment for the construction stage.

Keywords: inclined bracing; extraordinarily long structure; finite element analysis; BIM design
