下刚上柔轻型门式刚架加层结构地震作用规律探讨
|
摘要
以振型分解反应谱法和结构振动理论为基础,通过算例分析,对下刚上柔轻型门式刚架加层结构的地震作用规律进行探讨,讨论加层部分刚度、质量等对加层后复合结构体系地震作用的影响,以期对此种结构抗震设计方法的研究提供依据,做出更合理的设计。
Based on mode-superposition response spectrum method and structural vibration theory, this paper not only discuss the influence of the mass and the stiffness of the adding parts to the new complex structures added stories by some numerical examples and discuss the seismic response rules of soft-upper-rigid-down structures with light-gauge steel portal frames but also put forward to the study of seismic analytical method and the design of this kind of structures.
