Abstract
An approximate analysis of the strain concentration of the beam flange near the joint to the column flange at beam-to-column connections in steel structure is presented. The application of this analysis to the beam-to-column connection of which column has a heavy section and an H-shape cross section. The analysis is upon the incremental theory. Hence, strain is calculated by the integration along the loading pass. An elastic incremental strain is calculated on the geometrical condition and a plastic incremental strain is calculated on the geometrical condition, material condition and load hysteretic condition. The accurecy of the analysis was verified by the comparison of the calculated results with the experimental results.
