- Abstract
Based on the static and fatigue test by two-way loads for the right-angle typesudden change supporting of steel crane beam,the stress of the plates for the sudden change support-ing and influence of the load circlative rate on the stress of web around the sudden change points arestudied. The characteristics of the fatigue failure of this crane beam are given a minute description.Some technieal measures are put forward in design and construction.
