Frequency Monitoring and Simulation Analysis for Historical Structures Being Retrofitted

Many historical structures now need to be retrofitted to meet the requirements of fast developing cities. To ensure the safety of a historical masonry building during its retrofitting, natural frequency of the structure was measured through ambient vibrating tests. A simulation model was established and used to evaluate the equivalent elastic modulus of the masonry based on the test results. The properties of the structure were identified and monitored by the tests and simulation. The proposed method is applicable in similar engineering practices.
