Test and analysis of anti-seismic performance of recycled concrete on top of high-rise buildings

Abstract

The anti-seismic performance of recycled concrete on top of high-rise buildings is influenced greatly by external environment. An analysis model for anti-seismic behavior of recycled concrete on top of high-rise buildings is proposed. The recycled concrete on top of high-rise buildings is divided into different layers, and anti-seismic signal at strong vibration signal of different level is separated to get the periodic characteristics variance of anti-seismic performance signal. Then, Doppler frequency shift parameters of the vibration signal are calculated to complete the anti-seismic performance test. The test results show that the anti-seismic performance of recycled concrete on top of high-rise buildings changes periodically.
