摘　　要：本文对水平地震力作用下的预制钢筋混凝土框架进行可靠性分析。首先分析预制框架结构中钢材料的力学性能指标,根据其指标设置胶黏剂指标,以保证框架结构具有基本的抗震性能。然后使用液压伺服动作器在试件上施加压力,通过DH3816静态应变仪器手动采集框架的应变数据,以保证试验的有效性。最后模拟地震环境,通过水平位移、滞回性能、能量耗散、刚度退化等指标,分析框架结构的可靠性。测试结果表明:在水平地震力的作用下,试件SJ-1的抗震耗能指标更低,可靠性更佳,说明加固后的混凝土框架结构抗震性能更佳,对于建筑结构的稳定建设具有重要作用。This paper analyzes the reliability of prefabricated reinforced concrete frames under horizontal seismic force is being conducted.Firstly,analyze the mechanical performance indicators of steel materials in prefabricated frame structures,and set adhesive indicators based on these indicators to ensure that the frame structure has basic seismic performance.Then a hydraulic servo actuator is used to apply pressure on the specimen,and the strain data of the frame is manually collected using the DH3816 static strain instrument to ensure the effectiveness of the test.Finally,simulate the seismic environment and analyze the reliability of the frame structure through indicators such as horizontal displacement,hysteresis performance,energy dissipation and stiffness degradation.The test results indicate that under the action of horizontal seismic force,the seismic energy consumption index of the SJ-1 specimen is lower and the reliability is better,which indicates that the reinforced concrete frame structure has better seismic performance and plays an important role in the stable construction of building structures.
