【摘要】 本文通过三个空心薄璧桥墩模型的拟静力加载实验,研究了空心高墩在低周反复荷载作用下的破坏机理,滞回特性,能量耗散。通过分析模型的滞回曲线,骨架曲线,粘滞阻尼系数,得出了空心薄璧桥墩在地震作用下一般呈弯曲破坏的破坏机理,耗能能力较好。更多还原

【Abstract】 Through three hollow thin bi pier model quasi-static loading experiments to study the mechanism of high hollow pier damage under cyclic loads,hysteretic behavior.energy dissipation.By analyzing the hysteretic model curves,skeleton curves,viscous damping coefficient,bi obtained thin hollow piers under earthquake destroyed the general failure mechanism was bent,energy dissipation capacity better.更多还原
