RESEACHES OF STRESS CONCBNTRATION PARAMETER ON THE STEEL CRANE BEAM WITN RIGNT ANGLE SUDDEN CHANGE HEIGHT NEAR SUPPORTS[J]. Journal of Civil and Environmental Engineering, 1994, 16(2). DOI: 10.11835/j.issn.1674-4764.1994.02.003.
Using the method of homogenous testing design this paper analyses a steel cranebeam with right angle sudden change height near supports of different geomitry parameters by the fi-nite elements.The part of height stress point and the stress con cen tration parameter in the beam arefound.After analysing more element nonlinear regression
the relationship between stress concentra-tion parameter and geomitry parameter is established.This paper also discusses both source ofanalysing result error and effect.
