英文摘要	Different simulation blasting vibration waves are obtained using MATLAB software to examine the dynamic response of concrete frame structure under a blasting demolition environment, avoid impact on surrounding buildings, and prevent the vibration damage of blasting demolition to buildings. Structural displacement and acceleration response of a concrete frame structure with different explosive energy and blasting center distance are discussed using SAP2000. Results show that (1) vibration response on top of the concrete frame structure reaches maximum under the blasting vibration wave; (2) the larger the explosive distance, the smaller the explosive vibration response, and (3) explosive vibration response increases with the increase of explosive energy. Therefore, moderate explosive energy should be used in demolition engineering to decrease the influence on surrounding buildings. Weak parts on top of concrete frame structures should also be strengthened further in structure design. © 2014 ejge.
