浙江大学紫金港校区西区图书馆结构设计

The Structural Design of the Library in the West Area of Zijingang Campus of Zhejiang University

浙江大学紫金港校区西区图书馆为兼具图书馆、档案馆功能的少柱大空间高层建筑,也是重点设防类建筑,采用框架剪力墙结构。文章分析了该项目的结构设计思路、抗震超限情况,介绍了该项目基于抗震性能的设计方法;然后利用SATWE和ETABS软件分别对结构进行计算分析,对比结构周期、楼层剪力、楼层位移比等参数,发现两种软件计算结构基本一致;最后利用PKPM-SAUSAGE软件进行大震作用下的结构动力弹塑性补充分析。结果显示,关键构件的损伤情况良好,结构性能满足预定性能目标要求。

The library in the west area of Zijingang Campus of Zhejiang University is a high-rise building with few columns and large space that serves as both a library and an archive.It is also a key fortification building and adopts frame shear wall structure.The structural design idea and seismic overlimit situation of the project are analyzed,and the design method based on seismic performance is introduced.Then SATWE and ETABS software are used to calculate and analyze the structure respectively.By comparing the parameters such as structural period,floor shear force and floor displacement ratio,it is found that the two software calculation structures are basically the same.Finally,the PKPM-SAUSAGE software is used to carry out the dynamic elastic-plastic supplementary analysis of the structure under the action of large earthquakes.The results show that the damage of the key components is good,and the structural performance meets the predetermined performance target requirements.
