摘要: 湘西邊城書本雕像源自沈從文《邊城》,采用空間異形鋼框架結(jié)構(gòu)體系,由 15 榀人字形剛架和縱向水平連系梁組成,單榀人字形剛架由內(nèi)頁人字形支撐柱、外頁展開方向曲形框架梁、內(nèi)外頁水平連接梁及外頁局部落地支撐柱組成,所有桿件之間均為剛性連接。 采用 SAP2000 軟件對書本結(jié)構(gòu)進(jìn)行整體受力和變形分析、穩(wěn)定性分析,對曲面板按拉彎或壓彎構(gòu)件進(jìn)行分析和設(shè)計。 分析結(jié)果表明,考慮曲面板剛度能有效提高結(jié)構(gòu)整體穩(wěn)定性及變形能力,結(jié)構(gòu)各項指標(biāo)均能滿足規(guī)范要求。 通過設(shè)置一端固定鉸支座、一端滑動鉸支座釋放柱底水平推力,解決因柱底拉桿尺寸過大引起的設(shè)計和施工難度問題。

Abstract: The book statue in Xiangxi Biancheng originates from the world of Shen Congwen’ s biancheng. The buildingadopts the spatial special irregular steel frame structure system, which is composed of 15 chevron rigid frames andlongitudinal horizontal connecting beams. A single chevron rigid frame is composed of chevron brace columns on the innerpage, curved frame beams in the unfolding direction of the outer page, horizontal connecting beams on the inner and outerpages and local floor support columns on the outer page, and all the members are rigidly connected to each other. TheSAP2000 software was used to analyze the overall stress, deformation and stability of the book structure, and to analyze anddesign the curved panel according to the tension bending or compression bending components. The analysis results showthat considering the stiffness of curved panel can effectively improve the overall stability and deformation capacity of thestructure, and all indexes of the structure can meet the requirements of the code. By setting hinged and sliding support atthe column base to release the horizontal thrust at the column bottom, the design and construction difficulties caused by theexcessive size of the pull rod at the column bottom were solved.
