慈溪文化中心南区包括博物馆、科技馆和文化中心三楼,其中文化中心大楼为3层框架结构,在第一层有夹层,通过地下室与博物馆和科技馆相连。该结构平面布置不规则且局部大开洞,外围柱子均为斜柱,属于平面不规则结构,通过布置防屈曲约束支撑来加强结构薄弱部位,使其满足规范要求。文章主要介绍该结构的设计分析情况,防屈曲约束支撑的布置,并详细介绍了斜柱的设计计算以及结构的构造措施。
Southern Cixi Cultural Center includes museums, science and technology centers and cultural centers on the third floor, of which the Cultural Center building has a three-story frame structure with a mezzanine on the first floor and is connected to museums and science and technology museums in the basement. The structure is irregularly arranged with large open holes in the plane. The external columns are inclined columns and belong to the plane irregular structure. The weak parts of the structure are reinforced by the buckling-restraining brace to meet the requirements of the specification. This article mainly introduces the design and analysis of the structure, the arrangement of anti-buckling restraint brace, and introduces in detail the design and calculation of inclined column and the structural measures.
