 note = {application/pdf, 論文(Article), This study is concerned with the demand for ductility of beams in steel moment frames. Numerical response analysis was carried out for 15 frames against a variety of ground motions. This paper (Part 1) describes the magnitude of plastic deformation introduced into beam-ends. Maximum plastic rotation, maximum increment of plastic rotation during a half-cycle of vibration, and the range of variable plastic rotation are considered as the parameters that represent the magnitude of plastic deformation. The results are summarized as formulas to predict those parameters based on maximum story drift angles., http://www.jssc.or.jp/},
