Abstract: Dynamic response of buildings under blasting vibration is the core of the blasting harmful effects research. The research results on the dynamic response of buildings to blasting vibration can be summarized in four main aspects. ① Blasting seismic wave propagation laws in different types of buildings are relatively different,building peak particle velocity in different directions at the same time with the attenuation and amplification effect. ② The building natural frequency exhibits multi-order characteristics. Building dynamic response is a complex process of mutual coupling between multi-harmonic seismic waves and buildings with multi-order natural frequency characteristics. ③ The damage of buildings under blasting vibration is categorized into structural and non-structural damage,initial and cumulative damage and other damage modes. ④ Peak particle velocity and main vibration frequency can basically reflect the whole picture of the blasting vibration impact on the building,but due to the diversity of the building structure and the complexity of the vibration response,the accuracy of the safety criterion does not yet meet the actual needs. The research directions focusing on the dynamic response of buildings under blasting vibration are presented. ① Attention should be paid to the propagation laws of blasting seismic wave,local amplification and attenuation effects of the different components of the building,as well as the blasting vibration response characteristics of the overall structure of the building and different components. ② The further studies should focus on the correlation between the building multiorder natural frequency and the overall structure and local components,the influence mechanism of the multi-order natural frequency and the blasting seismic wave multi-harmonic component on the resonance of the building structure and components. The response relationship model between the multi-harmonic components of blasting seismic wave corresponding to the dynamic properties of the overall structure and local components should be developed. ③ Adopting artificial intelligence method to establish an real-time monitoring platform for blasting vibration and structural damage,which integrating data acquisition,preprocessing,analysis,and early warning. ④ Determine the blasting vibration safety criteria for structural damage to the main structure of the building or non-structural damage to the attachments.
