对以往的试验研究进行了调查的对角钢支撑构件的非弹性响应进行循环非弹性荷载下的集中支撑钢框架的抗震设计，在地震下的延性反应是必需的收集数据。被检查的参数是支撑构件的屈曲强度，在各种延性水平下的支撑屈曲后抗压强度，支撑最大拉伸强度，包括应变硬化效应，以及屈曲时支撑的侧向变形。提出了这些参数的方程。此外，矩形空心支撑构件可以实现的最大延性进行了检查。(C)2002爱思唯尔科技有限公司版权所有。
A survey of past experimental studies on the inelastic response of diagonal steel bracing members subjected to cyclic inelastic loading was carried out to collect data for the seismic design of concentrically braced steel frames for which a ductile response is required under earthquakes. The parameters that were examined are the buckling strength of the bracing members, the brace post-buckling compressive resistance at various ductility levels, the brace maximum tensile strength including strain hardening effects, and the lateral deformations of the braces upon buckling. Equations are proposed for each of these parameters. In addition, the maximum ductility that can be achieved by rectangular hollow bracing members is examined. (C) 2002 Elsevier Science Ltd.
