摘　　要：自动化监测多层砌体结构抗震能力能够最大程度降低地震带来的损失,然而砌体结构的承受负荷和下沉量难以准确监测。为了解决上述问题,提升多层砌体结构抗震自动化监测效果,对基于无线传感技术的多层砌体结构抗震自动化监测模型进行设计。首先分析二维状态的砌块等效体积单元的应力-应变关系,进而判断得到的砌体受压应力-应变关系,确定监测点,再通过无线传感分析建立监测数学模型,利用信息采集对数据进行控制,实现抗震自动监测。实验结果表明,设计模型在受力超过临界值后,能够精准地判断出多层砌体结构所受荷载,监测的下沉量准确率在99.8%以上,具有一定的应用价值。Automatic monitoring of the seismic capacity of multi-storey masonry structures can minimize the losses caused by earthquakes,but it is difficult to accurately monitor the load and settlement of masonry structures.In order to solve the above problems and improve the seismic automatic monitoring effect of multi-story masonry structures,the seismic automatic monitoring model of multi-story masonry structures based on wireless sensor technology is designed.Firstly,the stress-strain relationship of the equivalent volume unit of the block in the two-dimensional state is analyzed,and then the obtained stress-strain relationship of the masonry under compression is judged,and the monitoring point is determined.Then,the monitoring mathematical model is established through wireless sensor analysis,and the data is controlled by information acquisition to achieve automatic seismic monitoring.The experimental results show that the design model can accurately judge the load on the multi-storey masonry structure after the stress exceeds the critical value,and the accuracy rate of monitoring the settlement is more than 99.8%,which has certain application value.
