摘要: The behavior of both structural steel and reinforced concrete specimens subjected to quasi-static cyclic loadings simulating severe seismic effects are examined. A large number experimentally determined hysteretic loops for different arrangements based on the work mainly done at University California, Berkeley, serve as illustrations. important distinction among material, member subassemblage ductilities is emphasized. significance character overall performance discussed by relating it widely-used response spectrum approach analysis. relationship latter conventional code design procedures also given.
