摘要
Abstract
To research the similarity law of shockwave characteristic parameters and the structural damage of the reinforced concrete( RC) structures under the internal explosion,the similarity theory model of the RC structure under the internal explosion is established, the similarity tests of the original model and the scale model with scale coefficient values of 0. 75 and 0. 5 are conducted,and the similarity law of the shockwave characteristics parameter and the structural damage of RC structures is analysed. The results show that the peak overpressure of similarity models in the typical locations under different charge weights has similar distribution characteristics. When the charge weights follow the similarity criteria,the maximum relative errors of the first peak overpressure and the scale pulse width of the first three peaks between the 0 . 75 scale model and the original model are less than 10. 33% and 4. 02% respectively. As the scale coefficient is 0. 5, the values are 5. 25% and 14. 36% respectively. Pressure-time history curves of the scale model are consistent with the original model,proving that the shockwave characteristic parameter of the scale models under the internal explosion obeys similar laws. The similarity scale models under the charge producing the same damage level can get the similar damage degree and failure modes.关键词
