A new seismic monitoring system for historical buildings was developed and tested in Isfahan, one of the oldest cities in Iran (read the Case Study, pdf). The system consists of R-sensors' seismometers and geophones and Geoarmatech's seismic recorders.
The research goal was to develop a new seismic monitoring system for historical buildings in Isfahan and compare the results of the general vibration assessment (by Federal Transportation Association, or the FTA method) measurements to the measurements at the vibration source.
For that goal, a 1-year vibrations monitoring was conducted. The solution included development of a new monitoring system consisting of analog seismometers CME-4211 and geophones MTSS-1001 (R-sensors) and recorders GeoArm-R24 (Arman Fanavaran Zamin also known as Geoarmatech).
The results confirmed feasibility of a new monitoring system which is providing more reliable predictions than those of the FTA measurements. The results also showed the water table level has a strong impact on vibrations and accuracy of predictions.
