考虑剪切变形影响的单跨曲线梁受力分析
Mechanical analysis of single-span curved beams considering shear deformation effect
摘要
Abstract
Based on the theory of Timoshenko deep beam and principle of force method,a calculation method about the single span curved beam considering the effect of shear de-formation is established,the internal forces and deformation formula of the single span curved deep beam under point load is deduced,and the derived formulas are verified by a functional example,then the rule of the single span curved beam under the influence of cen-tral angle,radius of curvature of shear effect influence of deformation is analyzed.Research results show that,single span curved beam under concentrated load with the change of the center angle,considering the effect of shear deformation of the deep beam theory and the theory of the primary beam without considering the influence of shear deformation,the re-sult of the deflection calculation is very large.With the change of the radius of curvature, the shear effect has a great influence on the deflection.Elementary beam theory is too low to estimate the effect of shear stress on the deformation of curved beam.关键词
