摘要
由于剪切变形对波形钢腹板箱梁挠度的影响不容忽略,根据悬臂状态下组合梁的受力特点,运用能量法考虑剪切变形挠度计算公式,通过建立有限元模型验证公式准确性及适用性,经验算,论文推导公式在精度上满足需要,可为同类桥梁简便计算提供参考。
The influence of shear deformation on the deflection of box girder with corrugated steel webs is ignored, according to the loading features of composite beam under the cantilever position condition, we derive the deflection calculation formula considering shear deformation using the energy method, through establish FEM to verify the accuracy and applicability of formula, after verification, the derivation formula meets the requirement of accuracy, can provide reference for similar bridge calculation.
