塑性铰区加强方式对高强混凝土剪力墙抗震性能的影响OA北大核心CSTPCD
Effects of strengthening methods in plastic hinge zone on seismic performance of high-strength concrete shear walls
为研究塑性铰区加强方式对高强混凝土剪力墙抗震性能的影响,首先,开展4片高强钢筋高强混凝土剪力墙的低周反复荷载试验与ABAQUS有限元模拟;其次,分析塑性铰区采用添加钢纤维、加密箍筋、外包钢板3种加强方式对剪力墙破坏形态、滞回特性、承载力与变形能力、强度与刚度退化、耗能能力以及塑性铰发展长度等方面的影响机理;最后,提出适用于高强钢筋高强混凝土剪力墙的等效塑性铰长度与承载力计算方法.研究结果表明:3种加强方式均有利于减轻墙体损伤程度,降低剪切变形占比…查看全部>>
To investigate the effects of plastic hinge zone reinforcement methods on the seismic performance of high-strength concrete shear walls,firstly,four high-strength concrete shear walls with high-strength reinforcements were designed to carry out low-cycle loading tests and ABAQUS finite element analysis.Secondly,the effects of three reinforcement methods with adding steel fibers,adding stirrups,and wrapping steel plates on the failure modes,hysteretic behavio…查看全部>>
