摘要: 蘭州理工大學(xué)西校區(qū)大學(xué)生活動(dòng)中心由劇場(chǎng)、報(bào)告廳和活動(dòng)中心三部分組成,建筑外觀以蘭州“天斧沙宮”景觀為原型,建筑造型較為復(fù)雜. 考慮到建筑功能及結(jié)構(gòu)布置的特殊性,該建筑結(jié)構(gòu)體系選用屈曲約束支撐-混凝土框架結(jié)構(gòu),采用 YJK 與 SAP2000 軟件對(duì)屈曲約束支撐-混凝土框架結(jié)構(gòu)、鋼支撐-混凝土框架結(jié)構(gòu)及混凝土框架結(jié)構(gòu)進(jìn)行對(duì)比分析. 結(jié)果表明:鋼支撐-混凝土框架結(jié)構(gòu)、屈曲約束支撐-混凝土框架結(jié)構(gòu)可有效控制結(jié)構(gòu)的扭轉(zhuǎn)不規(guī)則,為結(jié)構(gòu)提供側(cè)向剛度;在多遇地震下,屈曲約束支撐-混凝土框架結(jié)構(gòu)耗能效果并無(wú)顯著體現(xiàn);在罕遇地震下,屈曲約束支撐-混凝土框架結(jié)構(gòu)的滯回耗能效果明顯優(yōu)于鋼支撐-混凝土框架結(jié)構(gòu)和混凝土框架結(jié)構(gòu). 同時(shí)針對(duì)結(jié)構(gòu)薄弱部位采取了有效的抗震加強(qiáng)措施.

關(guān)鍵詞: 屈曲約束支撐-混凝土框架; 扭轉(zhuǎn)不規(guī)則; 耗能; 減震效果; 性能目標(biāo)

Abstract: College student activity center in West Campus of Lanzhou University of Technology consists of three parts:theater, lecture hall and activity center. The exterior of the building is based on the landscape of Tianfusha Palace inLanzhou,with a complex architectural shape. Considering the particularity of building function and structure arrangement,the structural system of the building adopts buckling-restrained braced(BRB)-concrete frame structure. The BRB-concreteframe structure, steel brace-concrete frame structure and concrete frame structure were analyzed by YJK and SAP2000software. The results show that the steel braced-concrete frame structure and BRB-concrete frame structure can effectivelycontrol the torsion irregularity of the structure and provide lateral stiffness for structure. The energy dissipation effect of theBRB-concrete frame structure is not obvious in frequently occurred earthquake. The hysteretic energy dissipation effect ofBRB-concrete frame structure is obviously better than that of steel brace-concrete frame structure and concrete framestructure in rarely occurred earthquake. At the same time, effective seismic strengthening measures were taken for the weakparts of the structure.

Keywords: buckling-restrained braced-concrete frame; torsion irregularity; energy dissipation; damping effect;performance objective
