Abstract: Sinusoidal corrugated web H-shaped members are composed of flanges and sinusoidal webs, and it has ahigher load-carrying efficiency than flat web especially as a beam. Based on the section simplified model of thesinusoidal corrugated web, the bend-carrying capacity and the shearing stability capacity of the sinusoidal corrugatedweb beams were proposed. Formula of beam deflection which considers the shearing deformation of sinusoidalcorrugated web was also presented. Two full scale tests of sinusoidal web members under bending were carried out, and loading process and failure mechanism of the beam were shown. Finite element analysis was used to certify thetest results, and the initial defect of members was also considered. It concludes that all of the test results went wellwith the FEA results, and both of them had confirmed the rationality of the proposed formula mentioned above.
