The goal is to determine how efficiently can this stiffener support the connected compressed plate. To consider local buckling of the compressed plate the effective widths will be calculated. These widths can be either calculated for a plate supported at both ends or for a plate supported at one end only, using Table 4.1 and Table 4.2, respectively.gate

In our series we continue with the second „secret” formula of EN 1993-1-3.
This formula (5.11) is used when the ability of an intermediate stiffener to stabilize a compressed web plate is studied.gate
