Abstract:
The previous research on the shear capacity of two forms of corrugated steel webs was summarized, and the formulas for calculating the local, global and interactive bucking loads of two forms of corrugated steel webs were proposed respectively, and recommended formulas were proposed by comparing of different formulas for calculating bucking loads. Based on results from numerical calculation analysis, the factors of the ultimate shear capacities of two H-section beams with corrugated steel webs were identified respectively, and the transforming conditions of them were proposed. Based on previous experiment data and results from numerical calculation analysis, the practical formulas for calculating shear stability coefficients of two forms of corrugated steel webs were provided. The results show that the wave height, flat sub-panel width, amplitude, wave length of H-section beams with corrugated steel webs should be a reasonable set, if the set is too large or too small, it will weak the ultimate bearing capacity of steel beams; the calculation results of the formulas for predicting the shear stability coefficients of two forms of corrugated steel webs are better fitting with the numerical results and experiment data, and the calculation is simple, easy to practical engineering design.
