STRENGTH OF WELDED SUPPORT JOINTS IN METAL STRUCTURES OF OVERHEAD CRANES

It has been established that under the conditions of low-cycle loading, the development of fatigue damage in the regions of welded joints is determined by interaction of the stresses, produced by an applied load, along with the residual stresses that have a marked effect on the actual characteristics of the cycle. Under the conditions of a pulsed cycle from tensile stresses, caused by applied loading, the residual compressive stresses in the concentrator zone can be responsible for decreased strength under cyclic loading. Measures are proposed for increasing the strength of the support assemblies in crane girders under alternating load.
