摘要: 澳門(mén)大學(xué)珠海校區(qū)禮堂結(jié)構(gòu)設(shè)計(jì)需同時(shí)滿足國(guó)家和地方的相關(guān)規(guī)范. 禮堂內(nèi)部空曠,樓層錯(cuò)落不齊,設(shè)置剪力墻可以讓各部分有相對(duì)獨(dú)立的較強(qiáng)的抗側(cè)力體系,也可以為樓座大懸挑梁提供穩(wěn)固的支撐. 計(jì)算結(jié)果表明,框架-剪力墻結(jié)構(gòu)的禮堂考慮觀眾席斜樓蓋的影響后,抗側(cè)剛度有一些增加,斜樓蓋下端的構(gòu)件及與其相連的柱內(nèi)力增大. 還介紹了屋蓋預(yù)應(yīng)力梁、樓座大懸挑梁等的設(shè)計(jì),對(duì)于大小跨梁引起的內(nèi)柱彎矩過(guò)大的問(wèn)題,通過(guò)合理選擇梁中預(yù)應(yīng)力筋線型,在內(nèi)柱產(chǎn)生與外荷載效應(yīng)相反的彎矩有效地予以解決.

Abstract:The structural design of the auditorium in Zhuhai Campus of University of Macau needs to meet the relevantnations and local regulations at the same time. The interior of the auditorium has open field and the floor is staggered.Setting the shear wall can allow each part to have a relatively independent strong lateral resistant system. It can also providea solid support for the large cantilever beam of the building. The calculation results show that after considering the influenceof the inclined floor of the auditorium, the lateral stiffness of the auditorium of frame-shear wall structure increases a little,and the internal force of the members at the lower end of the inclined floor and the columns connected with it increases. Thedesign of prestressed beam on roof and large cantilever beam on floor was also introduced. To solve the problem ofexcessively large bending moment of inner column caused by large and small span beam, the bending moment of innercolumn which was opposite to the effect of external load could be effectively solved by reasonable selection of profile ofprestressing tendon in beams.

Keywords: auditorium; house in open field; large cantilever; inclined floor; profile of prestressing tendon; secondarymoment of inner column
