针对结构中的局部复杂部位,需要进行良好的概念设计,还需要进行必要的补充分析。本文针对大跨采用空腹桁架进行转换的情况和大跨钢结构连廊存在自振频率不满足规范最小要求时需要做舒适度分析的情况进行了具体分析,得出了可供借鉴的结论。
For complex local parts of the structure, a good conceptual design is required and additional necessary analysis is required. In this paper, a detailed analysis is made on the situation of the need of comfort analysis when the natural frequency of large-span steel structure corridors is converted by the fasting trusses and the natural frequency is not satisfied with the minimum requirement.
