有很多复杂的分析方法可预测单层多跨钢框架的几何非线性和钢构件的材料非线性影响。然而,一些结构工程师在理解这些复杂的方法以及应用在钢结构设计上存在困难。因此,提供了简化的分析模型,用于初步设计阶段。采用简化的分析模型,结构工程师能够容易地预测层间位移、最大允许荷载,单层多跨钢框架支撑的刚度。通过二维的有限元分析验证了简化模型应用的可行性。
There are many complex analytical methods that predict the geometric nonlinearities of single-story, multi-span steel frames and the material nonlinear effects of steel components. However, some structural engineers have difficulty understanding these complicated methods and their application to the design of steel structures. Therefore, a simplified analytical model is provided for the preliminary design phase. Using a simplified analytical model, structural engineers can easily predict the displacement between layers, the maximum allowable load, and the rigidity of the single-story, multi-span steel frame support. The feasibility of the simplified model is verified by two-dimensional finite element analysis.
