摘要
该文介绍了楔形变截面工字钢短梁的抗剪承载力试验,与有限元结果进行了对比,提出了将楔形变截面梁的承载力按等截面梁的承载力乘以楔率折减系数的计算方法,与试验和扩充的有限元计算结果对比表明:公式有很好的精度。
The paper reported an experimental study on the post-buckling shear strength of I-sectional beams with tapered webs. The comparison with FEM （Finite Element Method） analysis is carried out and reasonable agreement between the test and the FEA （Finite Element Analysis） is observed. A design formula is proposed that the post-buckling shear strength is determined by multiplying the counterpart of the uniform beam by a taper reduction factor. The comparison with test and expanded FEM analysis shows an excellent effectiveness of the proposed formula.
