WebMar 5, 2024 · The lowest value of the buckling coefficient \(k_c = 3\) corresponds to two half-waves in the loading direction and one half wave in the transverse direction. It is seen that restricting the in-plane deformation does not change the buckling mode but reduces the buckling load by a factor of \(3/4\). The reaction compressive force makes the plate ... WebFrom the book of prof. Salmon For the first figure on the left side, the braced column, due to bracing, the k value is always <1, the joint is rigid, the angle between the girder and the column is 90 degrees, and this angle is kept unchanged and the K is <1, KL=0.7 L and < L. In all the cases, K<1, This is the case e of a frame with pinned support.
