Hysteretic Behavior of Steel Columns,

摘要

This is the third and concluding report on the project 'Inelastic Behavior of Beam-Column Subassemblages.'The previous reports were titled 'Inelastic Behavior of Steel Beam-Column Subassemblages' (1),October 1971,and 'Further Studies on Seismic Behavior of Steel Beam-Column Subassemglages,' (2),December 1973. The results of experiments with eight specimens are given in the above two reports. These specimens were designed with strong columns,so as to have inelastic (hysteretic) behavior in the beams and the panel zones. In this report,emphasis is placed on the strong inelastic (hysteretic) action in the columns of steel beam-columns subassemblages. A total of six specimens were tested. In four of these,the columns were bent around their strong axes;in two,around their weak axes. The main objective of these tests was to determine the behavior of column plastic hinges subjected to random pseudo-static cyclic loading. Some tentative conclusions are drawn from the results of the analyses presented.
