Abstract:In this study, a new test method is proposed to address the problem of low accuracy associated with the test results of the current seismic performance test methods with respect to concrete structures. A function family was obtained using the wavelet function, and a wavelet transform was carried out on the analog seismic signals. When the function family constituted a standard orthogonal basis, the seismic signal was reconstructed from the continuous wavelet transform. After denoising, the seismic signal was considered to be a signal sample for verifying the seismic performance of a concrete structure. The displacement response, velocity response, acceleration response, and restoring force were obtained using a dynamic equilibrium equation exhibiting a single degree of freedom. Further, the strength reduction coefficient and the maximum elastic response of the concrete structure were calculated. The experimental results exhibited that the proposed method can effectively test the seismic performance of concrete structures with a high accuracy.
