I am developing an android application (system) which measures the building vibration and calculates its natural frequency. I was planning to map these natural frequencies and during a disaster, this application can be used for risk assessment. But since only magnitude of an earthquake is known it seems impossible to compare the earthquake frequency and building natural frequency. I referred many articles, but I was unable to find what can be done if only the natural frequency of the building is known. If anybody have some idea about this matter, please share me. I will be grateful for any help you all can provide. |
