| 通过四种不同双向加载规则的钢筋混凝土高墩拟静力试验,初步研究了双向拟静力加载规则对其滞回特性的影响规律。本文主要介绍钢筋混凝土高墩的试验构件设计,加载装置、测试方法和加载规则,着重比较了对角线加载、正方形加载、菱形加载和圆形加载等四种加载规则的钢筋混凝土高墩的滞回性能,包括荷载-位移滞回曲线、荷载-位移骨架曲线、荷载退化、刚度退化以及累积滞回耗能的特点,并分析这些特点与双向加载规则之间的关系。结论认为：对角线加载模式加载效率高且能较好反映高墩双向抗震滞回性能,适合于高墩的双向拟静力试验研究。 |

| The influence of bidirectional quasi-static loading rule on the hysteretic properties of reinforced concrete high pier was preliminarily studied by bidirectional quasi-static test of four reinforced concrete high piers. The tested specimens design, loading devices, testing method and loading rules were firstly introduced in this paper. The bidirectional quasi-static test of reinforced concrete high piers was carried out with four different loading patters: diagonal loading patter, square loading patter, diamond loading patter and circle loading patter. Hysteretic characteristics, including load-displacement hysteretic curves, load-displacement skeleton curves, load degradation, rigid degradation as well as accumulative hysteretic dissipated energy were emphatically compared, and the relationship between hysteretic characteristics and load rules was analyzed. It is concluded that the bi-directional hysteretic properties were well obtained by using the diagonal loading rule, so this loading rule is available and recommended in bidirectional quasi-static test for reinforced concrete high pier. |
