摘要 传统建筑结构抗震性能分析方法忽略了对建筑结构不同结构点的测量,导致传统方法无法有效监测到建筑结构的受力钢筋黏结应变、滞回曲线和延性系数,出现监测精度低问题。为此,提出强震冲击下建筑结构抗震性能及变形监测方法。分析建筑材料抗震性能,测量建筑结构不同结构点,采集建筑结构变形值,构建建筑结构变形模型。通过对回归平面以及变形状态的计算,完成强震冲击下建筑结构抗震性能及变形监测。实验结果表明,所提方法能够有效监测出建筑结构受力钢筋黏结应力、滞回曲线以及延性系数,且变形监测精度较高。 The traditional seismic performance analysis method of building structure ignores the measurement of different structural points of building structure,resulting in the traditional method can not effectively monitor the bonding strain,hysteretic curve and ductility coefficient of stressed reinforcement of building structure,resulting in the problem of low monitoring accuracy.Therefore,the monitoring method for seismic performance and deformation of building structures under strong earthquake impact are proposed in this paper.The seismic performance of building materials was investigated in detail,and different structural points and deformation values of the building structure were measured and collected,founding the deformation model of the building structure.According to the calculation results of regression plane and deformation state,the monitoring of seismic performance and deformation of building structures under strong earthquake impact was achieved.The experimental results show that this method has high deformation monitoring accuracy,and can effectively obtain the bonding stress,hysteretic curve and ductility coefficient of stressed reinforcement in building structure.
