[摘要]將對稱平直線加腋梁簡化為以橫截面形心的連線為中性軸的空間曲桿,推導(dǎo)了其解析解。給出了這種加腋梁在均布荷載作用下的計(jì)算參考表格,并通過實(shí)例和三維有限元的數(shù)值解進(jìn)行了對比,提出了對稱平直線加腋梁解析解的修正方法。將對稱平直線加腋梁和對稱斜直線加腋梁進(jìn)行了對比和分析,得出了一些有意義的結(jié)論。

Abstract:Symmetric parallel-haunched beams are simplified to spacial curved beams whose neutral axes are geometrical centers of the cross-sections, and the mathematic solution and reckoner of the beams under uniform load are given. An example is given to demonstrate the solution by the finite element analysis, and the modified method about the mathematic solution is proposed. The comparison between parallel-haunched beams and diagonal-haunched beams is made, and some practical conclusions are got.
Keywords:parallel-haunched beam; uniform load; mathematic solution; modified method
