摘要

摘要: 通过循环反复加载试验研究了3个带钢端头的新型装配式高强钢筋混凝土梁柱中节点的受力性能,分析该高强钢筋混凝土梁柱中节点的破坏特征、弯矩-转角、核心区剪力-转角、强度退化以及应变规律。根据试验结果发现,设计的新型装配式高强钢筋混凝土梁柱节点均呈现出预期设计的节点核心区剪切破坏。预埋钢连接件与钢筋混凝土梁之间的连接可靠,带钢端头装配式高强钢筋混凝土梁柱节点中能够有效传递内力,显现出较高的转动能力和较平缓的强度退化,节点受力性能良好。钢端头中横隔板和设置的腹板受力充分,可与箍筋和混凝土分担受力。3个被测试构件中水平连接板间设置腹板且装配部位后浇混凝土的节点受力性能最佳。

Abstract: Three new fabricated high-strength reinforced concrete beam-column joints with steel ends were subjected to quasi-static loading tests to investigate their mechanical properties. The failure characteristics moment-rotation hysteresis curves, sheared-rotation skeleton curves in core area, strength degradation, and strain laws of the joints were analyzed. The test results showed that the proposed new prefabricated high-strength reinforced concrete beam-column joints occurred the expected shear damage in the core area. The connection between the embedded steel connectors and reinforced concrete beams was reliable. The prefabricated high-strength reinforced concrete beam-column joints with steel ends could effectively transfer internal forces, showing high rotation capacity and gentle strength degradation. Thus the joints showed a good mechanical properties. The spacer and the web set in the steel end could be stressed with the stirrups and concrete. The joint with webs between horizontal connecting plates and post-cast concrete in the assembly area exhibited the best mechanical properties among the three specimens.
