Consideration of Imperfections in Combination Expressions

WitrynaNormally, the equivalent imperfections are defined in a separate imperfection load case, which can then be added in a load combination accordingly. If you generate a pre-defined initial model, the shifted FE nodes can be applied as parameters for the calculation of a load combi-nation. This has the advantage that the model data is not … 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.
