Experimental Study of H Steel Beam Deformation Monitoring Based on BOTDA
分布式光纤传感测试系统(BOTDA)用于H型钢梁变形监测的实验研究

Principle of strain measurement based on Brillouin optical time domain analyzer(BOTDA)is introduced and the strain distribution of a loaded H steel beam was measured by using BOTDA.Experimental results show that the strain measured by BOTDA is in good agreement with theoretical value and that measured by resistance strain gauge.Optical measurement data is continuous and therefore is more suitable for those structures that need to test their continuous deformation.The calculated bending moment and the deflec...
