Estimate the strength of concrete by calculating the elastic modulus from the shear wave velocity!
We would like to introduce the "Shear Wave Velocity Measurement Work for Gravity Dams." The purpose is to estimate the strength of concrete by calculating the elastic modulus from the shear wave velocity. Accelerometers were placed in the inspection gallery of the gravity concrete dam, and vibrations were applied using a hammer near the reference point, measuring the acceleration during this process. The impact vibrations were separated into cases for P-wave velocity and S-wave velocity, with more than five vibrations conducted for each case. The sampling frequency of the recording device was set to over 10 kHz, and the time history waveforms of the accelerometers were recorded. 【Measurement Overview】 - Accelerometers were placed in the inspection gallery of the gravity concrete dam, and vibrations were applied using a hammer near the reference point, measuring the acceleration during this process. - Impact vibrations were separated into cases for P-wave velocity and S-wave velocity, with more than five vibrations conducted for each case. - The sampling frequency of the recording device was set to over 10 kHz, and the time history waveforms of the accelerometers were recorded. *For more details, please download the PDF or feel free to contact us.*
