摘要
介绍了对某生产厂房的动力特性现场测试和对厂房结构的模态分析及谐响应分析结果。在掌握该厂房振动规律的基础上,针对厂房结构的特点提出增设钢斜撑的方法进行加固处理。并用有限元方法进行了计算分析和加固效果评估。
This paper introduces the measurements on dynamic properties of a industrial structure and the results of modeshape and harmonic response analyses of the structure. To reduce the vibration displacement, a method that strengthens the structure by adding diagonal steel brace is presented on the basis of the measured dynamic properties and the characteristics of the structure. In addition, the structure is analyzed by finite element method, and its strengthen effect is evaluated.
