The symmetry limit theory, originally developed for beam-columns with uni-axial constitutive relations, is extended to elastic-perfectly plastic continua in the shakedown region. In the symmetry limit theory, we trace the steady-state path, or the va

SUMMARY Criteria are presented for assessing the propensity for dynamic collapse of elastoplastic structural systems. To detect the onset of dynamic collapse, three key concepts are introduced. First, the equations of motion are linearized and time s

For elastoplastic trusses under quasi-static cyclic loading, a method is presented for finding the steady-state limit that bounds the plastic shakedown and ratchetting regions. In the plastic shakedown region, an assumption employed in the previous a

Experimental works are done to assess the seismic behavior of concrete beams reinforced with superelastic alloy (SEA) bars. Applicability of newly developed Cu-Al-Mn SEA bars, characterized by large recovery strain, low material cost, and high machin

In Japan, near-fault earthquakes have been recorded frequently in resent years, e.g., Hyogoken-Nambu (1995, M7.3), Tottoriken-Seibu (2000, M7.3), Geiyo (2001, M6.4), Niigataken-Chuetsu (2004, M6.8), Fukuokaken-Seihouoki (2005, M7.0), Notohanto (2007,
