Research on Nonlinear Prediction Method for Touchdown Vibration Effect induced by Structural Collapse

Sun Pingyu;Liu Jun;Key Laboratory of Ministry of Education for Geomechanics and Embankment Engineering,Hohai University;Institute of Engineering Safety and Disaster Prevention,Hohai University;  
Demolition blasting has been widely used in the demolition of a building,but at present,about the touchdown vibration effects of structural collapse during demolition,there is no proven effective method of prediction and evaluation.Based on the theory of nonlinear science,a nonlinear prediction model based on Volterra functional series is created.The model can predict touchdown vibration effect induced by the collapsed building hitting superficial soil before the structural collapse.The model can fully reflect the nonlinear response characteristics of rock and soil media under the impact loading.At the same time,based on the nonlinear Volterra model of independent pulsed loads,a simplified identification method is put forward.The practical engineering application shows that the predictions and the measured results match well and the application of the model is simple.There is some significance to prevent and reduce the harm of vibration effects arisen from structural collapse hitting the ground.
