某老年大学音乐教学楼减震设计

Seismic design of music teaching building in an elderly university

针对《建设工程抗震管理条例》(国务院令第744号)第十六条地震重点监视防御区的新建学校应当按照国家有关规定采用隔震减震等技术,由于本项目为老年大学音乐楼并且所在地区为重点监视防御区,所以按照规范要求采用消能减震技术;项目所在地区设防烈度为7度,结构主体本身刚度较好,所以采用墙式连接黏滞阻尼器减震方案。主要介绍黏滞阻尼器设计思路和方法,通过PKPM和SAUSAGE软件一体化设计,采用中震弹性时程分析更便捷求解出阻尼器附加阻尼比,同时进行大震弹塑性时程分析结构塑性发展较好,各项指标满足规范要求,且阻尼器滞回曲线饱满,具有良好耗能能力,保证结构设防地震正常使用要求。

For the Seismic construction project management regulations(State Council Decree No.744),Article 16 of the newschool in the key seismic surveillance and defense zone should adopt seismic isolation and damping technology in accordance with the relevant national regulations,because this project is a music building of the senior citizen university and the area is a key surveillance and defense zone,so the energy dissipation and damping technology was adopted in accordance with the code requirements;the project is located in an area with intensity of 7 degrees,and the main structure itself has good stiffness.Since the intensity of the project is 7 degrees,the main body of the structure itself has good stiffness,so the wall-connected viscous damper damping scheme is adopted.The design ideas and methods of viscous dampers are mainly introduced,through the integrated design of PKPM and SAUSAGE software,the additional damping ratio of dampers is solved more conveniently by medium-earthquake elastic time analysis,and the structural plasticity development is better by large-earthquake elasto-plastic time analysis,and the indicators meet the requirements of the code,and the hysteresis curve of dampers is full,with good energy dissipation capacity,to ensure the normal use of the structure for earthquake protection.The requirements are as follow.
