摘要
本文讨论了幕墙立柱设计、计算中常用的双跨梁模型。对不同短跨与长跨比对双跨梁剪力、弯矩、挠度影响做了详细的计算,给出了一般性的定量公式,并根据施工实际情况做了具体分析,合理的选取最佳比例。最后通过实际的工程利用大型通用有限元软件ANSYS对计算结果进行了模拟,结果表明软件结果与计算结果接近,可以直接用理论计算结论在幕墙设计中进行立柱的设计与计算,为立柱设计提供了一般性的理论工具。
The calculation of common two-span beam models in curtain column design and calculation was dis- cussed, then a detailed calculation of the impact of different short and long span ratioon shear, moment, deflec- tion of two-span beam was made and general quantitative formula was given, and a specific analysis was made ac- cording to actual situation, then a optimal ratio was chosen. The final part of the project is simulating the calcu- lation results by using the large finite element software ANSYS , the results show that the software and calculated results are close. The calculated results can directly apply to the design and calculation of the curtain wall. It provides a general theoretical tool for the design of column in the future.
