Abstract:
A finite element internal explosion model of reinforced concrete structure was established and a comparative analysis with experimental data was conducted. On this basis, numerical simulation analysis was carried out on a two-story three-span frame structure considering different explosion yields and blast source positions. The damage correlation relationship among components, floors and the overall structure was proposed, and a method for evaluating the damage degree of the overall structure through the importance of components and floors was established. Considering the uncertainty distribution of the blast source, the blast vulnerability analysis of slabs, beams, columns and the overall structure was carried out. The results shows that when the blast source is located at any position within the room, the damage probability of slabs is the highest, followed by beams, and columns have the lowest probability. The vulnerability values of moderate and severe damage of slabs are both larger than those of beams and columns, but the vulnerability value of moderate damage of columns is greater than that of severe damage of beams. When considering the uncertainty of the blast source position, the components of the first floor are more prone to damage than those of the second floor. For the overall frame structure, at a yield of 27.8 kg, the difference between the vulnerability of light damage and moderate damage is the largest, reaching 31%. As the yield increases, at a yield of 75 kg, the difference between light damage and moderate damage is within 5%. At a yield of 57.7 kg, the difference between moderate damage and severe damage is the largest, reaching 62%.
