【摘要】 设置耗能自复位铰节点（EDSC-HJ）的钢筋混凝土框架结构是一种新型韧性结构体系。首先，介绍了EDSC-HJ框架结构的基本构造和有限元建模方法；其次，介绍了耐震时程法的基本原理，采用耐震时程法对EDSC-HJ框架结构和常规钢筋混凝土框架结构（RCF）的抗震性能进行了数值模拟对比研究。研究结果表明：节点相对转动刚度比在[0.2, 0.5]范围内，不同节点刚度的EDSC-HJ框架结构地震作用下的动力响应变化明显，过大的节点刚度将导致EDSC-HJ框架结构的性能趋近于RCF结构；罕遇地震下，EDSC-HJ框架结构通过弱化节点约束，最大基底剪力响应和最大加速度响应相比于RCF结构分别降低了68%和76%，最大层间位移响应上升了19%，但仅为设计限值1/20的31.5%；相比于RCF结构，EDSC-HJ框架结构强震下的可修复性能显著提高。更多还原

【Abstract】 The reinforced concrete frame with energy dissipating self-centering hinge joint(EDSC-HJ) is a new type of resilient structure. Firstly, the basic construction and the modeling method of finite element model for EDSC-HJ frame are introduced. Secondly, the fundamental principle of the endurance time method is presented. The seismic performance of the EDSC-HJ frame and the conventional reinforced concrete frame(RCF) are compared through the utilization of the seismic time-history method. The results show that the dynamic responses of EDSC-HJ frame with different joint stiffness changes significantly under earthquake action when the relative rotational stiffness ratio of nodes is within the range of [0.2, 0.5], and excessive node stiffness will lead to the seismic performance of EDSC-HJ frame approaching that of RCF structures. Under rare earthquakes, the maximum base shear responses and the maximum acceleration responses of the EDSC-HJ frame decrease by 68% and 76%, respectively, compared to the RCF structure. The maximum inter story displacement responses of the EDSC-HJ frame increases by 19%, which is merely 31.5% of the design limit of 1/20. Compared with the RCF, the repairability of the EDSC-HJ frame under high intensity is significantly improved.更多还原
