Imperfection load
WitrynaUnlike stub columns, the initial geometric imperfection is one of the factors that can remarkably influence the behavior of slender columns. The overall geometric imperfections can cause load eccentricity, which can become of importance in … WitrynaThe columns are 4 m high and the imperfection is defined as L/200, which corresponds to 20 mm. This leads for the left and right column, respectively, to the following notional loads The 1 st order relative deformations of 1D members show the direction in which the notional loads are to be applied. Special case: no 1 st order curvature
