回字形环山地建筑结构设计

Structural design of square-ring shape building on the slope

中央美院青岛创业中心项目为角部重叠的回字形山地建筑,采用了框架-剪力墙结构体系。主体建筑结构总高度为54m,坐落在三个台地上,每两个相邻台地高差10m左右。掉层处采用"掉层脱开式且有拉梁"的方式进行结构布置。结合山地建筑结构的基本概念和受力特点,介绍了本项目的结构处理方式和设计难点,采用PKPM,MIDAS Building, SAUSAGE软件对结构进行了弹性反应谱法分析、弹性时程分析、动力弹塑性时程分析和抗震性能设计,同时针对各种不利因素采取了相应的加强措施,确保了结构安全。

Qingdao Venture Center project of the Central Academy of Fine Arts is a square-ring shape building with overlapping corners on three slopes,and frame-shear wall structure system is adopted.The main building structure has a total height of 54 m and is located on three terraces slopes a height difference of about 10 m between every two adjacent slopes.The structure is arranged in the way of"dropping off the floor and arranging the beams".According to the basic concepts and stress characteristics of structure on the slope,the structural treatment methods and designed difficulties of the project were introduced.Programs PKPM,MIDAS Building,SAUSAGE were used to conduct the elastic response spectrum analysis,elastic time history analysis,dynamic elastic-plastic time history analysis,and performance-based seismic design.Corresponding strengthening measures have been taken for various unfavorable factors to ensure structural safety.
