摘要

摘要:
为实现钢筋混凝土框架结构震后损伤小、快速修复及恢复其使用功能的要求，设计3榀1/2缩尺的混凝土框架（1榀为普通钢筋混凝土框架，2榀为配置高强钢棒的混凝土框架）进行拟静力试验，研究混凝土框架结构在往复荷载作用下的破坏形态，探讨梁柱等构件配置高强钢棒后对框架结构的滞回曲线、骨架曲线、残余变形、可修复性等抗震性能指标和自复位能力的影响. 研究结果表明：框架梁柱中配置高强钢棒可有效提高框架结构的整体承载能力和变形能力, 与普通钢筋混凝土框架相比，试件NHGS2.5A15和试件HGHGS2.5A15表现出良好的位移硬化效应，其极限承载分别提高23%和57%，极限荷载对应的位移也分别提高50%和60%；其残余变形小，可修复率高，具有良好的自复位能力和可修复性.

Abstract:
To realize the requirements of minor post-earthquake damage, rapid repair, and functional recovery of reinforced concrete frame structures, three 1/2 scaled concrete frames were designed. One was an ordinary reinforced concrete frame, and two were concrete frames reinforced with high-strength steel bars (HG bars). Quasi-static tests were carried out to study the failure modes of the frames under cyclic loading. The effects of beams and columns with HG bars on seismic performance indexes including hysteretic curves, skeleton curves, residual deformation, repairability, and self-centering ability, were discussed. The results show that the use of HG bars in beams and columns effectively improves the overall bearing capacity and deformation capacity of the frame. Compared with the ordinary reinforced concrete frame, specimens NHGS2.5A15 and HGHGS2.5A15 show good displacement hardening effects. Their ultimate bearing capacities increase by 23% and 57%, respectively, and the displacement corresponding to ultimate load increases by 50% and 60%, respectively. These specimens have smaller residual deformations and higher reparability, and they demonstrate good self-centering capability and repairability performance.
