摘要
本文针对典型工字梁结构,基于弯曲刚度等效方法 ,且保持截面形心不变,通过PATRAN软件建立有限元模型,分别建成10段等长的梁单元和板杆结构(腹板简化为剪切板元),分析工字梁弯曲变形挠度和梁截面上内力分布,验证板杆结构工程算法的准确性。
For the typical I-beam structure, based on the equivalent bending stiffness and the same cross section centroid, two finite element models were established by PATRAN. The I-beam structure was simplified as 10 equal-length beam elements and plate-rod structures which the webs were simplified as shear plate elements. The deformation and the internal force of the I-beam were analyzed to verify the accuracy of the engineering algorithm of the plate-rod structure.
