位于北海公园湖西侧的北京图书馆东楼工程,地处市内秀丽的风景区,附近还有大量的古建筑群。为和周围环境及城市规划协调,采用了琉璃瓦大屋顶。建筑立面图见图1、2、3。建筑结构按八度抗震设防,全部为现浇钢筋混凝土框架。由于使用了现代结构,在建筑构造设计时我们最感困难的问题,是大屋顶的挑檐部分。
Located on the west side of Beihai Park Lake, the Beijing Library East Building is located in the beautiful scenery of the city, and there are a large number of ancient buildings nearby. In order to coordinate with the surrounding environment and urban planning, a large glazed roof was used. The elevation of the building is shown in Figures 1, 2, and 3. The building structure is quake-proofed by octaves, all of which are cast-in-place reinforced concrete frames. Due to the use of modern structures, the most difficult issue for us in the design of architectural structures is the provocative part of the large roof.
