通过对相关技术标准水平风荷载作用下的单层轻钢结构临建房屋结构骨架及整体分析,将有限元分析结果与试验结果进行比较,保证有限元模型的准确性。使用经过验证的有限元建模方法对两层及三层轻钢结构临建房屋进行结构整体分析,考察结构侧移与相关技术标准要求的差距,揭示墙面板对多层房屋整体结构的刚度起到的有利作用,在设计中通过考虑这种作用可减少材料用量及建造成本。采用通用钢结构分析软件进行结构简化分析,提出考虑墙板作用的等效交叉支撑实用设计方法,给出等效支撑直径的取值公式,并提出设计建议。
By comparing the finite element analysis results with the experimental results, the structure of the single-storey light steel structure and the overall analysis of the building under the horizontal wind load of the relevant technical standard are compared to ensure the accuracy of the finite element model. The structural finite element analysis of two-story and three-story buildings with light steel structures is conducted by using the finite element modeling method verified. The difference between structural sideshifts and related technical standards is examined to reveal the influence of the wall panels on the rigidity of the whole structure of multi-story houses The beneficial effect of reducing the amount of material used and the cost of construction by considering this effect in the design. The structural simplification of common steel structure analysis software is used to analyze the practical design method of equivalent cross-bracing considering the action of wall panels. The formula of the equivalent bracing diameter is given and the design proposal is proposed.
