EFFECT OF LOADING HYSTERETIC PROGRAM ON PLASTIC DEFORMATION CAPACITY AND CUMULATIVE PLASTIC DEFORMATION CAPACITY FOR H-SHAPED BEAM WITH LOCAL BUCKLING

Abstract

In general, the seismic capacity of H-shaped beams with the local bucking is estimated by the two main structural factors. One of them is the plastic deformation capacity in the skeleton curve, and the other is the cumulative hesteresis energy in cumulative hesteresis loops. Their correlation has not been shown even though each one has been individually used as the seismic capacity of the beams. In this paper, the correlation between the cumulative hesteresis energy and the plastic deformation capacity of H-shaped beams are experimentally investigated in 11 test series and the empirical equations based on the previous experimental results are suggested.
