ENGINEERING TECHNIQUE OF CALCULATION OF SHOCK LOAD OF LOAD-HOISTING CRANE FOR DEFINITION OF THE INITIAL DATA IN CALCULATIONS OF THE BUFFER DEVICE
In the article the questions of the calculation of shock load that appears when hoisting crane runs over fixed buffer are considered, the evaluation of this load is given and the necessary raw data for calculation of buffers are given.
This paper presents a comprehensive work to evaluate the long-term influence of concrete on the shear-lag effect in steel–concrete composite beams, for which rather few tests and numerical studies have been reported. The FE study demonstrates that the effective width is greatly influenced by the analytic models: linear creep (CnSnC model) linear creep with shrinkage (CSnC model) creep with shrinkage and cracking (CSC model). Some numerical results were not well clarified, as discussed in the following.
