【摘要】 以西安长庆石油勘探局科研楼钢结构塔楼工程设计为例,从工程设计的角度阐述高层建筑楼顶上加钢结构塔这一目前很多工程中经常遇到的设计问题,如不采取适当的减震控制措施,通常变形很难达到规范的要求。计算表明:本工程设置粘滞流体阻尼器后,在地震和风的作用下,能分别满足变形的要求,另外还对减震器安装位置的确定及连接件的设计进行了详细的阐述,供同类结构设计及计算借鉴、参考。更多还原

【Abstract】 Design problems are expatiated in this paper for the steel tower appended on the top of the high-rise building by taking example for a steel tower project design. Generally, without proper shock absorption devices, it is difficult to meet the requirements of the criterions. In this project, shock absorption devices are installed. The computation indicates that under the earthquake and wind the strength and displacement meet the criterions after installing the fluid viscous dampers. The position for devices installation and design of connections are discussed in detail. It can be used for reference for design and computation of similar projects.更多还原
