Abstract
The effectiveness of the base-isolation technique for the mitigation of structural response under earthquake and wind forces has been widely investigated. The response of a building under surface blast loading is critical, as in that case the structure is subjected to both the high magnitude air pressure and ground shock effect. In the present study, the usefulness of the base-isolation technique in reducing the structural damage caused by the surface explosion is investigated. For this purpose, non-linear time history analysis of the 3D model of a six-storey building under surface explosion loading is performed. Responses of the building under the fixed-base condition and isolated-base condition are compared to investigate the effectiveness of base isolation in mitigating the surface blast effect. Also, the effect of base-isolator parameters on its performance is investigated. Results of the study show that base isolation can be useful in mitigating the surface explosion effect on a building if a proper selection of isolator parameters is made.
