摘要:澳门大学珠海校区礼堂结构设计需同时满足国家和地方的相关规范。礼堂内部空旷,楼层错落不齐,设置剪力墙可以让各部分有相对独立的较强的抗侧力体系,也可以为楼座大悬挑梁提供稳固的支撑。计算结果表明,框架-剪力墙结构的礼堂考虑观众席斜楼盖的影响后,抗侧刚度有一些增加,斜楼盖下端的构件及与其相连的柱内力增大。还介绍了屋盖预应力梁、楼座大悬挑梁等的设计,对于大小跨梁引起的内柱弯矩过大的问题,通过合理选择梁中预应力筋线型,在内柱产生与外荷载效应相反的弯矩有效地予以解决。

Abstract: The structural design of the auditorium in Zhuhai Campus of University of Macau needs to meet the relevant nations 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 provide a solid support for the large cantilever beam of the building. The calculation results show that after considering the influence of 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. The design of prestressed beam on roof and large cantilever beam on floor was also introduced. To solve the problem of excessively large bending moment of inner column caused by large and small span beam, the bending moment of inner column which was opposite to the effect of external load could be effectively solved by reasonable selection of profile of prestressing tendon in beams.
Keywords: auditorium; house in open field; large cantilever; inclined floor; profile of prestressing tendon; secondary moment of inner column
