HRBF500级钢筋混凝土柱恢复力模型
|
摘要
以HRBF500级钢筋混凝土柱的拟静力试验为出发点,针对尚无合适于HRBF500 RC柱的恢复力模型的现状,提出了500 MPa细晶粒高强钢筋混凝土柱的理论骨架曲线。运用理论及经验公式法确定各个阶段的特征点,并提出了卸载刚度的经验公式和滞回规则。经验证,所提出的骨架曲线模型与试验值吻合良好,具有一定的准确度和代表性。
Based on quasi-static test,a theoretical skeleton curve of HRBF500 RC columns was presented to change the status that there is not any appropriate restoring force model for HRBF500 RC columns.Characteristic points in various stages were determined by theoretical or experimental methods,including unloading stiffness and hysteretic rules.The theoretical skeleton curve was in good agreement with the test one and it was proved to be reliable and representative.
