TO THE ASSESSMENT OF VERTICAL CRANE LOAD
Journal Title: International Journal for Computational Civil and Structural Engineering - Year 2019, Vol 15, Issue 1
Abstract
The problems of analytical and statistical modeling of the travelling cranes loads are carried out in the paper. The analytical model was expanded by the consideration of influence of the approach of cranes trolley, consideration of zero realization areas and crane impact zones which allowed to precise the statistical characteristics of the vertical crane loads. The numerical modeling which takes into account the accidental position of the crane bridge and position of the trolley on the crane bridge was used for the calculation the vertical crane loads from the four-wheel cranes. Comparison of the results showed that the design value of the vertical load per wheel is rarely realized. This fact should be used to clarify the crane load combination factors.
