摘要
轻钢龙骨体系是一种新型的轻钢结构体系,在我国具有很好的应用前景。本文针对轻钢结构自身特点,提出合理的简化建模方法,对相同开间数不同高宽比的结构模型分别进行模态分析和时程分析,研究高宽比变化对结构整体抗震性能的影响。结果表明:随着高宽比的增大,结构整体抗侧移刚度减小,抗震性能逐渐变差,并就本论文所分析的结构模型对不同抗震设防烈度区域提出合理的设计建议。
The web light-gauge joist steel system is a new type of steel structure,which has a very good application prospect in our country.According to the characteristics of extremely web steel structure,reasonable simplified modeling methods are put forward.Modal analysis and time history analysis for the same width and with different aspect ratios of structural model respectively are conducted to study the impact on the whole structural seismic performance by aspect ratio change.Results indicate that the overall resistance to lateral stiffness decreases,and that seismic performance gradually becomes poor with the increase of aspect ratio.Meanwhile,some reasonable design proposal is recommended for the structure model of different seismic fortification intensity area.
